California boasts one of the most extensive and diverse road networks in the world. From busy urban freeways in Los Angeles to quiet scenic byways winding through redwood forests, the Golden State’s roads offer a bit of everything. Santa Clarita Valley drivers, in particular, experience this d iversity first-hand – local streets connect to major highways that can take you from the mountains to the sea. In this comprehensive guide, we’ll explore California’s roads by category and region: major highways, scenic routes, local Santa Clarita streets, and even some unique roadside attractions. Along the way, we’ll discuss typical driving conditions, notable landmarks, and tips (like choosing the right tires) to ensure a smooth journey.  Major Highways and Freeways in California  California’s backbone is formed by its Interstate highways and major US routes, which facilitate long-distance travel and daily commutes alike. These high-capacity roads are vital for commerce and connectivity, linking cities and regions across the state.  Interstate 5: The Main North–South Artery  Interstate 5 (I-5) is California’s primary north–south freeway, stretching roughly 797 miles from San Ysidro at the Mexican border to Hilt at the Oregon state line​. It is the longest interstate within California and carries motorists through a variety of landscapes. In Southern California, I-5 is known as the Santa Ana Freeway through Orange County and the Golden State Freeway through Los Angeles County (including Santa Clarita). As it climbs over the Tejon Pass north of Santa Clarita – an area locally known as “The Grapevine” – I-5 reaches high elevations where winter weather can be a concern. In fact, heavy snow can temporarily shut down the Grapevine section of I-5, as happened during a January 2025 storm when authorities closed the freeway for safety​. Santa Clarita residents are familiar with such closures “north of Santa Clarita” and know that when I-5 over the Grapevine is impassable, alternative routes like US 101 become the detour​. Once past the Grapevine, I-5 straightens out across the Central Valley farmlands for hundreds of miles. This stretch (often called the Westside Freeway in the Central Valley) is less scenic but important for through-travel. It’s a heavily used trucking route, and while generally flat, summer heat here can be intense. For those long, hot highway drives, ensure your vehicle’s cooling system and tires are in good shape – touring tires designed for highway durability and comfort (which often have lower rolling resistance for better fuel economy​) are a smart choice. High-quality touring tires (for example, the Yokohama Avid Touring-S or similar models) can provide a smooth, fuel-efficient ride mile after mile.  Locally, I-5 is central to Santa Clarita’s connectivity. It bisects the Santa Clarita Valley north-to-south, providing a route south into the San Fernando Valley and Los Angeles, and north toward Bakersfield. Within the SCV, I-5 is typically busy with commuters. Major interchanges like Magic Mountain Parkway (serving Six Flags Magic Mountain) and SR-14 (the Antelope Valley Freeway) see a lot of merging traffic. Northbound out of Santa Clarita, I-5 ascends into the Tejon Pass (4,144 feet) – a steep grade known for challenging big-rigs. In winter, the California Highway Patrol may escort traffic or require chains in this section if ice and snow accumulate. When snow hits the Grapevine, Caltrans often initiates “Operation Snowflake,” temporarily holding or diverting traffic​. Fortunately, such extreme weather is infrequent; most of the time, the challenges on I-5 are more likely to be heavy traffic or summer tire blowouts from heat. Travelers should always carry water and an emergency kit on this long stretch, and consider all-season touring tires that handle sustained high speeds and hot pavement.  Interstate 10: East–West from the Pacific to the Desert  Interstate 10 (I-10) is the principal east–west interstate in Southern California. Starting at the Pacific Coast in Santa Monica, I-10 (the Santa Monica Freeway and later the San Bernardino Freeway) cuts across the heart of Los Angeles. It passes through downtown L.A. – one of the most congested segments – then continues east through the Inland Empire cities of San Bernardino and Palm Springs, eventually reaching the Arizona border. Locals know that the I-10 commute through L.A. can be brutal; multi-lane traffic jams are a daily routine on this freeway.​   As you drive eastward, urban congestion gives way to open deserts. The freeway traverses arid Coachella Valley towns (Indio, for example) where blowing sand occasionally reduces visibility. In summer, desert stretches of I-10 regularly see temperatures above 110°F, so vehicles and tires should be prepared for extreme heat. All-season tires in good condition (with proper inflation) are a must – the scorching pavement can be tough on worn tires. If your travels on I-10 will take you into Arizona or beyond, remember that this interstate climbs significantly in elevation toward Arizona’s high plateaus; weather can change quickly in winter months.  For Santa Clarita residents, I-10 isn’t directly connected to our valley (we’re roughly 40 miles north of its nearest point), but many SCV travelers hop on I-10 when heading to Palm Springs, Phoenix, or other points east. To get there, one typically takes I-5 or I-405 south from Santa Clarita to the I-10 interchange in L.A. Given Los Angeles traffic patterns, planning those trips during off-peak hours is wise.  Interstate 15: Gateway to Las Vegas and the Inland Empire  Interstate 15 (I-15) is another critical north–south route, especially for those in Southern California headed to Las Vegas or the recreational areas of the Mojave Desert. Starting near San Diego, I-15 runs north through the Inland Empire (passing cities like Corona, Riverside, and San Bernardino). After climbing the Cajon Pass (connecting the Inland Empire to the high desert), I-15 continues through Victorville and Barstow before crossing into Nevada. The portion from greater L.A. to Barstow is sometimes humorously called the “Vegas pipeline” for the endless weekend traffic of Angelenos driving to Las Vegas. Expect very heavy traffic on Friday evenings northbound (and Sunday afternoons southbound) on this road – it’s almost a ritual exodus.  North of Barstow, I-15 enters a remote desert. One quirky landmark along this stretch is Zzyzx Road, an off-ramp in the middle of nowhere that gained fame for its peculiar name. Zzyzx Road leads into the Mojave National Preserve area and was the site of a former mineral springs resort. Today it’s largely a research outpost (the Desert Studies Center at Soda Springs) but still a fun curiosity for travelers. The road itself is partly unpaved and ends at the remnants of the old spa near Soda Dry Lake. If you venture down Zzyzx Road, be prepared for a 4-5 mile journey on gravel – and consider the condition of your tires. An all-terrain tire can handle the loose gravel better than a low-profile performance tire. In fact, for any such off-freeway desert exploration, equipping your vehicle with all-terrain tires like the BFGoodrich All-Terrain T/A KO2 is wise. These tires offer excellent traction on dirt and gravel, and they’re designed to resist punctures from sharp rocks​. With an aggressive tread and tough sidewalls, all-terrains can give you confidence on unpaved Mojave trails where standard street tires might risk a flat.  Weather-wise, I-15’s Cajon Pass (around 4,200 feet) can get occasional snow or fog, but it’s generally open year-round. More often, wind is an issue – strong crosswinds near the Mojave could affect high-profile vehicles. In summer, the open desert segment from Barstow to Nevada is extremely hot (as with I-10, carry water and check your spare tire). One piece of good news: unlike some California highways, I-15 is mostly free of tolls and you won’t encounter any until Nevada (where I-15 remains toll-free as well).  U.S. Highway 101: The Historic Coastal Route  US Highway 101 (often just “101”) is a legendary highway running along the California coast and through major cities. In the Los Angeles area, the 101 is a busy freeway (the Hollywood Freeway/Ventura Freeway) that passes through downtown L.A. and the San Fernando Valley. It then heads west and north, roughly tracing the coastline (though often a few miles inland) through Ventura and Santa Barbara. North of Santa Barbara, 101 becomes a scenic rural highway, meandering through California’s Central Coast wine country, the Salinas Valley, and eventually reaching the Bay Area and beyond.  For Santa Clarita drivers, Highway 101 is accessible by taking SR-126 west to Ventura (more on SR-126 later) or by taking I-405 or I-5 south to where they meet the 101 in L.A. Many locals use US 101 as an alternate north–south route when I-5’s Grapevine is closed – indeed, during Grapevine snow closures, officials often advise drivers to use 101 up the coast​. While 101 is longer in distance than I-5 for reaching Northern California, it stays at low elevation near the ocean (avoiding snow) and offers prettier scenery. The trade-off can be heavy traffic in urban segments and some two-lane stretches that slow down travel.  Notable along Highway 101:  Santa Barbara: 101 runs right along the waterfront for a short stretch; a beautiful drive but expect congestion as it passes through the city.  Central Coast: Between roughly San Luis Obispo and Salinas, US 101 passes rolling hills, vineyards, and ranches. It’s mostly four-lane divided, with relatively light traffic compared to SoCal freeways.  Bay Area: 101 is a major artery through San Jose and San Francisco (including the approach to the Golden Gate Bridge). In San Francisco, 101 actually goes right through city streets for a portion (Van Ness Avenue) before crossing the iconic Golden Gate Bridge into Marin County.  North Coast: North of the Bay Area, 101 once again becomes a scenic rural highway, winding through redwood forests of Humboldt and Del Norte counties – earning its nickname “Redwood Highway.”  Driving conditions on 101 vary from wide freeway to narrow curvy highway. Through the redwoods in Humboldt County, 101 narrows and even has some at-grade intersections. One highly recommended detour in that region is the Avenue of the Giants, a parallel old alignment of 101 that takes you through magnificent groves of giant redwood trees. This 31-mile scenic road is considered “the most outstanding display of giant trees” along California’s redwood belt​. It’s well-marked as a scenic alternative, and you can rejoin 101 at the end. (If you have the time, definitely take it – just mind the low speed limits and watch for tourists stopping to hug the trees!) The Avenue of the Giants was even voted one of the nation’s top five scenic drives​, and it’s easy to see why. Driving through Humboldt Redwoods State Park on the Avenue of the Giants – a peaceful 2-lane road flanked by towering coast redwoods. This old stretch of Highway 101 is a must-see scenic route for nature lovers​. In rainy conditions, be cautious of slick roads under the redwood canopy, and keep your headlights on – the tall trees can make it dusky even at midday.  For tires on Highway 101: in urban parts (L.A., Bay Area), responsive performance tires or all-season tires with good wet traction are useful, as you’ll be dealing with stop-and-go traffic and sometimes rain (especially up north). On the curvier rural sections, some drivers enjoy a spirited drive – just remember that high-performance tires will improve handling​, but obey speed limits especially on curves. If you plan to road-trip the entire coastal route, prioritize comfort and reliability. A set of grand touring tires could be ideal, offering long tread life and a smooth ride for the many miles, plus solid traction in varied weather​.  Other Important Interstates: I-405, I-80, and I-40  While I-5, I-10, I-15, and US 101 form the core, several other highways merit attention:  Interstate 405 (I-405): This busy freeway branches off I-5 in Orange County and rejoins I-5 near Santa Clarita (the junction is at Sylmar). The 405 is famously one of the most congested highways in the U.S., running along L.A.’s west side. Santa Clarita commuters sometimes take the 405 to reach West Los Angeles or LAX airport. Expect slow traffic through the Sepulveda Pass at rush hour. The 405 is all about city driving – full of lane merges and short on scenic beauty – but it’s critical for accessing coastal L.A. areas. Keep an eye out for motorcycles lane-splitting (common in California traffic) and buy high-performance all-season tires from trusted sellers like NeoTires, SimpleTire, Discount Tire, and Tire Rack if possible, since sudden braking and maneuvering in dense traffic are routine (performance tires provide superior handling and traction for quick lane changes​).  Interstate 80 (I-80): In Northern California, I-80 is the main route from the Bay Area to Lake Tahoe and on to Nevada. Starting in San Francisco (where it crosses the Bay Bridge), I-80 goes through Sacramento and then ascends the Sierra Nevada, cresting at Donner Summit (about 7,200 feet). This is one of the most snow-prone highways in California. Caltrans works hard to keep I-80 open year-round over Donner Pass​, but blizzards can and do close the road temporarily or require chain controls in winter. If you’re heading to Tahoe in ski season, always carry tire chains or have winter-rated tires. (California’s chain requirements mandate chains in certain conditions even on 4WD vehicles if they don’t have snow.) Fortunately, I-80 is a well-built freeway, and in good weather the drive is straightforward – though steep in parts and often busy with trucks. On dry pavement, no special tire is needed, but in snow, a set of all-weather or winter tires (with the mountain snowflake symbol) or at least having chains is strongly recommended. The scenery as you crest Donner Pass is stunning, with views of Donner Lake and surrounding peaks. Just don’t get too distracted – keep eyes on the road, especially if conditions are slick. If conditions deteriorate, be prepared for delays; it’s not uncommon for traffic to be held due to spinouts​. The motto for winter I-80 travel is “check conditions before you go.” Caltrans’ QuickMap and highway information line are great resources for that.  Interstate 40 (I-40): I-40 begins at Barstow (where it splits from I-15) and runs east to Arizona. It effectively continues the path of the historic Route 66 across the Mojave Desert. While I-40 doesn’t pass near Santa Clarita, it’s notable for travelers heading to the Grand Canyon or the Southwest. Towns like Needles and landmarks like the Colorado River are along I-40’s route. This is a fairly remote interstate – make sure your gas tank is full leaving Barstow, as services can be sparse for long stretches. In summer, the heat is extreme. In winter, high desert elevations can get a dusting of snow or black ice at night, but major closures are rare. If you’re an off-road adventurer, you might exit I-40 to explore Route 66 ghost towns or the Mojave Trails – here again, all-terrain or mud-terrain tires would be advisable. For example, accessing the remote ghost town of Amboy or the lava beds at Pisgah Crater involves driving old segments of Route 66 that are potholed and partially abandoned. A tough tire like the BFGoodrich Mud-Terrain T/A KM3, which is built for extreme off-road traction and durability​, can be a good choice if you plan to venture far off the beaten path in these areas.  Interstate 210 (I-210): Often called the Foothill Freeway, I-210 runs along the northern edge of L.A. It connects with I-5 near Santa Clarita’s southern edge (at the Newhall Pass) and goes east through Pasadena and onward to the Inland Empire. For Santa Clarita, the I-210 is another route to reach Pasadena, Glendale, and other San Gabriel Valley locales without driving through downtown traffic. The 210 often has smoother flow than the 10 freeway alternative, but it can still back up during peak hours. As it skirts the San Gabriel Mountains, the 210 offers glimpses of the peaks and, on clear days, views of the L.A. basin. Driving it is typical freeway fare; just be aware of occasional strong winds near the San Fernando Pass and debris from hillside brush (especially during Santa Ana wind events).  These major highways form the skeleton of California road travel. They’ll get you to most regions efficiently, but they’re only part of the story. Let’s now explore the scenic routes and byways – the roads you take when you’re not in a hurry, or when you want the journey itself to be the destination.  Scenic Routes and Iconic Byways  California’s varied geography – from coastline to high mountains to desert – means there are countless scenic drives. Some are well-known tourist routes, while others are local favorites for weekend outings. Here we cover some of the most notable scenic roads, including those connecting to or near Santa Clarita.  Pacific Coast Highway (Highway 1)  No discussion of California roads is complete without Highway 1, the Pacific Coast Highway (PCH). This legendary road hugs the coastline for over 650 miles, offering dramatic views of the Pacific at every turn. For much of its length, Highway 1 is a designated Scenic Highway. Key stretches include Orange County’s beach towns, the cliff-hugging route through Big Sur, and the winding shorelines of Marin and Mendocino counties.  In Southern California, Highway 1 starts in Dana Point (Orange County) and passes through L.A. ‘s beach cities (where it’s known as Sepulveda Blvd or Pacific Coast Hwy through places like Malibu). North of Los Angeles, PCH continues through Oxnard and Ventura (briefly merging with US 101), then splits off again from 101 near San Luis Obispo to become the famed Big Sur coast road up to Monterey. This Big Sur segment is often considered the crown jewel of PCH: a narrow two-lane road clinging to sea cliffs, with sights like Bixby Creek Bridge and numerous vista points overlooking the ocean. It’s an engineering marvel and a driver’s delight – but also requires caution. The road has sharp curves and steep drop-offs with minimal guardrails in some areas. Landslides are an ongoing concern; it’s challenging to keep the entire stretch open year-round due to the precarious coastal geology​. In fact, long portions have been closed in recent years after major slides, and as of late 2024, a section near Lucia remained closed with repairs not expected to finish until 2025​. Always check Caltrans updates if you plan a continuous drive through Big Sur, as detours might be required due to slide repairs.  Despite these occasional closures, the allure of PCH is undeniable. The Big Sur drive offers “unparalleled ocean views from a roadway carved through coastline cliffs”​ – it’s considered one of the world’s great scenic drives. Beyond Big Sur, Highway 1 passes through Monterey, Santa Cruz (where it turns inland), then rejoins the shore around Half Moon Bay and runs up the San Francisco Peninsula (known there as Cabrillo Highway). It crosses the Golden Gate Bridge (co-signed with 101 at that point) and later splits off into the rural coastline of Sonoma and Mendocino. North of Fort Bragg, it heads inland and terminates, feeding into US 101 to continue your northbound journey.  Driving conditions on PCH vary widely:  In city stretches (e.g., through Malibu or through Santa Monica), it’s a busy arterial with traffic lights. Expect slow traffic on sunny weekends as beachgoers flock to the coast.  In the Big Sur and far northern sections, it’s a two-lane mountain road. Uphill drivers should use turnouts to let faster traffic pass. Summer brings RVs and caravans of tourists, so patience is key. Winter can bring heavy rain and mudslides. Some portions have no cell signal and few services, so fuel up beforehand.  Motorcyclists love PCH for its curves, and cyclists also frequent it, so share the road carefully on blind turns.  For tires on PCH: the road surface can be rough in spots due to constant erosion repairs. A comfortable touring tire with good wet grip is ideal, as coastal fog and drizzle can make pavement slick. If you’re driving a sporty car to fully enjoy the curves, performance tires will enhance your experience, giving you better cornering stability as you snake along the cliffs. Just keep in mind that some parts of PCH are remote – having a dependable tire (with a spare ready) is more important than ultimate performance. A flat tire on a desolate Big Sur stretch means a long wait for help. It’s not a bad idea to carry a portable tire inflator or patch kit for peace of mind.  Mountain Passes and High Country Roads  California’s Sierra Nevada range is crisscrossed by a few high mountain highways that are attractions in themselves. These roads often close in winter, but in summer they offer access to alpine scenery, crystal clear lakes, and even national parks.  Tioga Road (Highway 120 through Yosemite): Tioga Road is the lone road that crosses Yosemite National Park east-west, connecting Yosemite’s Valley and Sierra foothills to the Eastern Sierra (where it meets US 395 near Lee Vining). At its summit, Tioga Pass, the road reaches 9,945 feet – making it the highest highway pass in California. The drive is stunning: you’ll see granite domes, forests, and high meadows. Highlights include Tuolumne Meadows and views of Tenaya Lake. Tioga Road is typically open only from late May/June through October; heavy snowfall forces its closure in winter​. Always verify the opening status if you plan a trip near the shoulders of the season. Driving Tioga is generally easy (the grade is moderate and the road is paved and well-maintained), but keep your vehicle in low gear on long descents to avoid overheating brakes. If traveling early or late in the season, be prepared for very cold nights and possible sudden snow flurries – even in June or October. A set of all-season tires with good tread is usually sufficient in summer months, but if you’re caught in an early snow, you might need chains. Also note: there are no services on Tioga Road inside Yosemite, so get gas in Lee Vining or before climbing from the west side.  Sonora Pass (Highway 108) and Ebbetts Pass (Highway 4): These are two other trans-Sierra routes north of Yosemite. Both are steep, narrow, and very high (Sonora Pass is over 9,600 ft, Ebbetts over 8,700 ft). They are scenic but challenging drives – except hairpin turns, no center stripe in some segments (especially Ebbetts Pass), and seasonal closure (generally closed November through May). These roads are popular with adventure motorcyclists and sports car drivers. If you tackle them, do so in daylight and good weather. The views of jagged peaks and deep canyons are incredible, but keep your focus on the road. Because of steep grades, RVs and trailers are discouraged (and in some cases prohibited). Similar to Tioga, bring what you need (water, etc.) as services are minimal. The high altitude can also affect your car’s performance (thin air = less engine power). As for tires, all-terrain tires can be useful if you plan to venture onto any dirt side roads or trailheads off these highways. Otherwise, any quality tire in good condition will do – just ensure your brakes and cooling system are in top shape for the climb and descent.  Angeles Crest Highway (State Route 2): Closer to Santa Clarita, the Angeles Crest Highway is a treasured scenic drive through the San Gabriel Mountains, just south of the SCV. It begins in La Cañada Flintridge (near Pasadena) and traverses 66 miles of mountainous terrain through Angeles National Forest, reaching elevations over 7,000 feet. Many Santa Clarita residents know this route as a recreational drive or a way to Wrightwood. It’s often simply called “Angeles Crest.” The road is well paved but very winding with sheer drop-offs in places. In winter, portions frequently close due to snow – it’s not maintained for all-weather travel. In summer, it’s a favorite of car clubs and bikers thanks to its curves and vistas. Key points include Mount Wilson Observatory turn-off and Newcomb’s Ranch (a now-closed historic roadhouse that was a popular stop). Driving tip: Watch for rockfall on the roadway – small rocks frequently tumble down onto Angeles Crest, especially after rain or freeze-thaw cycles. For spirited driving here, a performance tire with strong grip and responsive handling (like the Michelin Pilot Sport 4S, known for maximizing sports car performance​) can elevate the experience. Just be sure to stay safe and share the road with cyclists and motorcyclists, who are common. Enforcement by CHP is also something to note; speeding is taken seriously, so enjoy the road responsibly.  Rim of the World Scenic Byway (Highways 18 and 38): In the San Bernardino Mountains (further east in SoCal), the “Rim of the World” byway is a route that offers panoramic views of the valleys below. It passes by Lake Arrowhead and Big Bear Lake. If you’re in the Santa Clarita area, getting there involves a drive on I-210 and SR-18. Once ascending, you’ll encounter many switchbacks. In winter, chain requirements are common as these towns get significant snowfall. The roads are maintained, but they are mountain roads with all the usual cautions (steep drops, tight turns). Up in Big Bear, off-road opportunities abound – those with 4x4s might venture onto dirt forest roads or even to off-road parks. If that’s on your agenda, mud-terrain tires or aggressive all-terrains (like BFGoodrich KM3 or Goodyear Wrangler MT/R) will be beneficial for traction in mud or on rocky trails. Otherwise, normal all-season tires will handle the paved roads fine; just ensure they have the M+S rating and sufficient tread if you expect snow​ (California requires at least 6/32” tread on driven tires for them to count as “snow tires” in chain control areas).  Desert and Backcountry Drives  The vast deserts of California – the Mojave and Colorado deserts – offer their own kind of beauty. Two notable scenic drives out in the desert:  Joshua Tree National Park: Park Boulevard/Keys View Road within Joshua Tree NP form a scenic loop from the town of Joshua Tree to Twentynine Palms. It’s not a single highway with a name, but it’s a very popular drive to see the iconic Joshua trees, rock formations, and sweeping desert vistas. The roads are paved. Summers are extremely hot, winters mild (occasional light snow). Standard tires are fine, but if you plan to explore unpaved side roads (like the Geology Tour Road or Old Dale Road), you’ll want a high-clearance vehicle and possibly off-road tires. Also, Joshua Tree has no gas inside the park – fill up in town.  Death Valley National Park: Several paved roads traverse Death Valley NP, including CA-190 which cuts east-west through the heart of the park. Driving CA-190, you’ll descend to Badwater Basin (the lowest point in North America at -282 feet) and climb over two mountain ranges. It’s stark but awe-inspiring. Summer temperatures here can reach a world-record 130°F in the shade, so this drive is best done in cooler months (or very carefully in early morning or late evening during summer). Carry extra water for both you and your car. The heat can be brutal on cooling systems and tires – make sure yours are not worn out or underinflated. In such conditions, consider a reinforced all-season tire or light-truck tire if driving an SUV, as they handle heat better. If you venture onto Death Valley’s famous off-road routes (like Titus Canyon or Racetrack Playa – which absolutely require high-clearance 4×4), then mud-terrain or maximum traction tires are the order of the day. Regular street tires will not survive long on the sharp rocks. We’d recommend something like the BFGoodrich Mud-Terrain T/A KM3, which is built with tougher sidewalls and tread for rocky terrain​. On these trails, puncture resistance is crucial.  Finally, a fun one: The Musical Road. Not exactly a grand scenic byway, but a curiosity nonetheless – in Lancaster (north of Santa Clarita in the Antelope Valley), there is the Civic Musical Road. As you drive over specially cut grooves in the asphalt, your car’s tires will play a tune: the finale of Rossini’s “William Tell Overture” (a.k.a. the Lone Ranger theme). This was a gimmick originally created for a Honda commercial, and the city preserved it as a novelty​. It’s located on Avenue G between 30th and 40th Street West. Many Santa Clarita families take a little detour to experience it when visiting the Lancaster area. Fair warning: it only “plays” at about 50 mph, and the tune is a bit off-key due to mis-spacing of the grooves​. Still, it’s a neat roadside attraction. Driving over it won’t harm your tires, so no special equipment needed – just keep your windows down to hear the music!  Santa Clarita Valley Roads and Streets  Shifting focus to the Santa Clarita Valley (SCV) specifically, we find a mix of suburban city streets, historic old roads, and critical regional highways. Santa Clarita is uniquely situated at the crossroads of I-5 and SR-14, making it a gateway between Los Angeles and points north. Here’s what you should know about our local roads:  Highways Serving Santa Clarita  Interstate 5 through Santa Clarita: As discussed earlier, I-5 cuts through the west side of the SCV. Locally it’s often referred to as simply “the 5” or the Golden State Freeway. Key interchanges in SCV include Calgrove Blvd (southern end in Newhall), Lyons Ave, McBean Parkway (near the Valencia town center), and SR-126/Newhall Ranch Road (near Six Flags Magic Mountain). Traffic on I-5 in our valley can be heavy during rush hour, as many residents commute south to L.A. in the morning and return north in the evening. Northbound backups also occur on Sunday afternoons as people return from weekend trips (especially when holiday traffic from down south merges with local traffic). Santa Clarita itself is not typically a source of major jams, but incidents on the Grapevine or at the I-5/SR-14 interchange can ripple down. Driving tip: Mind the speed going through Santa Clarita – the freeway has some rolling hills; the CHP does monitor for speeders especially around the Newhall Pass area. Also be aware of trucks; lots of big-rigs use I-5 and they sometimes struggle on the grades, leading to slow right lanes. Maintaining a safe following distance is important. If you do a lot of freeway commuting, a good set of grand-touring all-season tires can make daily drives quieter and more comfortable, while still providing long tread life for the high mileage you rack up.  State Route 14 (Antelope Valley Freeway): This highway branches off I-5 at the Newhall Pass interchange (at the south end of SCV) and runs northeast through Canyon Country and onward to Palmdale/Lancaster. For Santa Clarita, SR-14 is just as vital as I-5, since it serves the eastern side of the valley. The stretch through Santa Clarita is often just called “the 14.” It passes areas like Newhall (via the Newhall Ave exit), Sand Canyon, and Soledad Canyon Road in Canyon Country. SR-14 is a lifeline for commuters heading from SCV to the San Fernando Valley or downtown L.A. (via the merge onto I-5 or I-210). Historically, before SR-14 was built, Sierra Highway was the main route to L.A. (more on Sierra Hwy below). Today, SR-14 is a modern freeway, but it has its quirks: the Newhall Pass interchange where I-5 and 14 meet is a known traffic bottleneck during rush hour. Also, past SCV heading into Acton and Palmdale, high winds can affect travel, and occasionally brush fires have closed the freeway (especially near Agua Dulce). SR-14 is fairly steep in parts as it climbs out of Santa Clarita – trucks use it too, albeit fewer than on I-5. Pay attention to road condition alerts in winter, because if snow falls at lower elevations, the 14 through Agua Dulce can see a light dusting (rare, but it happens). If you are a commuter on SR-14, investing in quality performance all-season tires or summer performance tires (weather permitting) could improve your daily drive – the Antelope Valley Freeway has some long, sweeping curves and can be driven at 70+ mph when traffic is light, so a tire with good high-speed stability and wet traction (for the occasional rain) is beneficial.  State Route 126 (Santa Paula Freeway/Henry Mayo Drive): SR-126 connects Santa Clarita to Ventura. It begins at the junction with I-5 near Castaic Junction (by Six Flags) and heads west through the Santa Clara River Valley, passing Fillmore and Santa Paula, ultimately reaching US 101 in Ventura. For SCV residents, this is the route to the Pacific coast – our pathway to the beach, if you will. The first portion of SR-126 in Valencia is an expressway commonly called Henry Mayo Drive (or Newhall Ranch Road extension), and it serves developing areas of west Valencia. West of Santa Clarita city limits, SR-126 becomes a mix of 4-lane divided highway and some 2-lane sections as it goes through farming communities. It’s a pretty drive, with orange groves and views of the riverbed. However, be cautious: parts of 126 have at-grade crossings and have seen serious accidents in the past. There have been efforts to upgrade it fully to freeway standards. In the meantime, observe the speed limits and double-yellow no-passing zones. On holiday weekends, 126 can get busy with people driving between L.A. and Ventura County. Also note that tule fog can settle in the Santa Clara Valley in winter, drastically reducing visibility – slow down if you encounter fog. For this route, ensure your tires have good wet traction; winter storms can flood the roadside ditches and occasionally cause temporary closures. If you’re towing a trailer (perhaps heading to the beach with a boat), check that your tires (and spare) are in good shape – nothing worse than a blowout on a 2-lane stretch. Generally, though, SR-126 is an easy drive. Once in Ventura, you can hop on US 101 or visit the beach directly. Fun fact: SR-126 was once slated to continue east through Santa Clarita and connect to SR-14, but that extension (sometimes called the Cross Valley Connector) was never built as a freeway – instead, Newhall Ranch Road serves a similar purpose now on the surface level​.  Sierra Highway (Historic US 6): Before the freeways, Sierra Highway was the main road linking Los Angeles, Santa Clarita, and the Mojave Desert. It runs roughly parallel to SR-14. Today, Sierra Highway serves as a local arterial road through Santa Clarita (especially through Newhall and Canyon Country) and as an alternate route to the Antelope Valley. In the pre-freeway era, it was part of U.S. Route 6, an old transcontinental highway. In fact, before 1963, Sierra Highway was the primary route from SCV to L.A.​. Historic US 6 ran from Long Beach all the way to Massachusetts, earning the title of the “Grand Army of the Republic Highway.” Sierra Hwy carried that traffic over Newhall Pass via the old Newhall Tunnel. Today, driving on the Sierra Highway offers a more leisurely, historical trip. You can still see remnants of old landmarks (like the site of Beale’s Cut – a hand-cut passage through the pass from the 19th century​). For locals, Sierra Highway is the address of some classic eateries and film shoot locations​. Traffic is usually light once you’re out of the urban sections. If an accident shuts down SR-14, Sierra Highway becomes the go-to detour, so it’s good to know the route. The road is mostly two lanes each way in SCV, narrowing to two lanes total as it heads toward Palmdale. Any standard tire is fine, but if you have an interest in the history and might pull off onto dirt shoulders to read historical markers or explore, be mindful of nails or debris (old desert roadside stops can sometimes have them).  The Old Road (Golden State Highway): Alongside I-5 through the Santa Clarita Valley runs a local road often called “The Old Road.” This was part of the old US 99 before I-5 was built. Today, The Old Road connects Castaic, Valencia, and Newhall, running parallel to the interstate. It’s heavily used when there are incidents on I-5, as people divert to avoid freeway traffic. The Old Road passes by Magic Mountain, and you’ll find gas, food, and services along it in Castaic and near Valencia’s industrial center. It’s a lifeline if I-5 closes at the Grapevine – often the CHP will turn drivers back to use 101 instead, since The Old Road doesn’t continue over the mountains (it dead-ends by Pyramid Lake where I-5 occupies the old ridge route). For everyday use, The Old Road is just a convenient local corridor. Cyclists and joggers also frequent parts of it, so be alert. Pavement is generally good. No special tire considerations here – any car can handle The Old Road easily.  Santa Clarita City Streets and Canyons  Within Santa Clarita city, a well-planned network of arterial roads helps traffic flow. Some key thoroughfares:  Valencia Boulevard & Magic Mountain Parkway: East-west arterials in Valencia, each with multiple lanes. These roads handle traffic going to shopping centers (like the Valencia Town Center mall on Valencia Blvd) and to Six Flags Magic Mountain (on Magic Mountain Pkwy). They intersect with I-5 and The Old Road near Six Flags. During evening rush hour and park closing times, expect congestion on Magic Mountain Parkway. If you live locally, you know to avoid that area when a big event lets out. These roads are smooth and wide – nothing too tricky, though watch for pedestrians near mall areas. Good all-season tires are fine; just mind the occasional traffic light race – better to stop than wear out your brake pads or tires by pushing amber lights.  McBean Parkway: A major north-south road through Valencia connecting Stevenson Ranch (south of Valencia) to Saugus (north end). McBean goes by Santa Clarita City Hall, Henry Mayo Hospital, and College of the Canyons. It even has a unique roundabout (at Avenida Navarre) – one of the few in the area. Traffic flows well, but at peak hours the intersections (like McBean & Valencia Blvd) get busy. McBean also connects to the Copper Hill area via Newhall Ranch Road.  Soledad Canyon Road & Bouquet Canyon Road: These two are primary east-west routes through Canyon Country and Saugus, respectively, converging in central Santa Clarita. Soledad Canyon runs along the Santa Clara River and parallels SR-14 on the east side, serving many Canyon Country businesses and neighborhoods. Bouquet Canyon Road runs from central Valencia up through Saugus and into Bouquet Canyon itself (north of city limits it becomes a winding mountain road to Bouquet Reservoir). Within the city, Bouquet Canyon Rd is a typical surface street with shops, signals, etc. It is known for some traffic congestion near Saugus High School and the intersection with Newhall Ranch Road. Soledad Canyon Road is quite lengthy; its eastern stretches go into more rural canyon areas (and eventually intersect Sierra Highway far out). Driving either of these is straightforward city driving. If you continue on Bouquet Canyon Rd into the mountains (past the houses), it becomes an adventurous drive – very narrow in spots, following a creek. That section is scenic, but be cautious of fallen rocks and flash floods in stormy weather. All-terrain tires could be helpful if you explore deeper into the canyon on dirt spurs, but otherwise standard tires are fine.  Sand Canyon Road: An important exit off SR-14 and a route into quiet equestrian neighborhoods. Sand Canyon leads from the 14 freeway into eastern SCV. South of Soledad, it climbs into the San Gabriel Mountains and eventually meets the Angeles Forest Highway (another back route to the LA basin). The road is part residential, part scenic. Lots of cyclists enjoy Sand Canyon. It does have some tight turns as it heads into the forest. If you plan to drive the full length and connect to Angeles Forest Hwy, ensure your brakes and tires are ready for mountain curves.  One charming note: in Newhall, the city recently installed some “old town” style roundabouts and street improvements along Newhall Avenue and Main Street. This is the historic downtown area of Santa Clarita (Old Town Newhall). The streets are narrower and encourage slow driving – enjoy the atmosphere and watch for pedestrians. Parking on Main St. can be angled, and during events (like the car show or farmers market) the area might be closed to vehicles.  Local Tips and Tire Recommendations Recap  Santa Clarita Valley’s roads are generally well-maintained and modern, thanks to the city’s relatively young age and good planning. Traffic can be an annoyance but rarely the kind of gridlock seen in central L.A. The valley’s location, however, means we interface with big highways – so residents need to be highway-savvy. Here’s a quick recap of tire advice tailored to SCV and California driving conditions:  All-Season Touring Tires for Daily Driving: If your routine is commuting on I-5 or SR-14 and running errands on city streets, a set of quality touring tires is ideal. They offer a balance of comfort, long tread life, and all-season traction. For instance, tires like the Cooper CS5 Grand Touring or Yokohama Avid Touring-S are built for year-round use and a smooth ride​. These would serve well for Santa Clarita’s hot summers and occasional winter rainstorms, as well as that weekend trip up 101.  Performance Tires for Spirited Drives: Car enthusiasts in SCV who take advantage of roads like Angeles Crest or who simply want better handling on freeway ramps might consider ultra-high-performance tires (especially in summer months). The Michelin Pilot Sport 4S is a popular max-performance summer tire that provides outstanding grip and steering response​ . On the other hand, if you want something that can handle colder weather too, there are performance-oriented all-seasons. These tires can enhance safety as well – shorter braking distances and better emergency handling on our curvy canyon roads.  All-Terrain and Off-Road Tires: We’re lucky to have off-roading opportunities around (e.g., nearby Rowher Flats OHV area off Sierra Highway, or the fire roads in Angeles National Forest). If you drive a truck or SUV and love exploring, equip it accordingly. All-terrain tires (like the BFGoodrich All-Terrain T/A KO2 or Goodyear Wrangler All-Terrain Adventure) will give you traction on dirt, sand, and rocks while still performing well on pavement. They are a great choice for someone who might daily-drive their 4×4 but also hit trails on weekends. For extreme off-roaders, mud-terrain tires provide even more grip in loose terrain at the cost of some on-road noise. For example, the BFGoodrich Mud-Terrain KM3 features special compounds for rock climbing and mud slinging​– perfect if you venture to places like the Mojave Road or Rubicon Trail.  Winter Considerations: In Santa Clarita proper, snow is almost unheard of (very rare dustings that melt by morning). But because we travel – whether to local mountains, the Sierra Nevadas, or the Grapevine – SCV drivers should not ignore winter preparation. If you plan to ski or visit snowy areas, consider all-weather tires (which have a winter traction rating) or be ready with snow chains. On I-5’s Grapevine or SR-14 to Palmdale, a sudden storm can create hazardous driving for a short period. In those cases, chains might be required by law even for locals who don’t normally drive in snow​. It’s wise to carry a set when you know you’ll cross mountain passes in winter.  Conclusion  Santa Clarita’s readers have a unique vantage point on California roads – we reside at a hub where local, regional, and statewide routes intersect. Whether you’re commuting down the 5, taking a Sunday drive up the coast, or hauling your trailer out to the desert, understanding the characteristics of each road you travel is key to a safe and enjoyable journey. California’s roads can lead you from surf to ski on the same day, but they also demand respect: mountain passes can be treacherous in bad weather​, coastal highways require vigilance against landslides​, and city freeways test one’s patience in traffic. By planning ahead, maintaining your vehicle (especially those tires that connect you to the road), and adapting to conditions, you can confidently navigate “California roads” in all their forms.  So, fuel up and hit the road – there’s a lot to explore. As you drive through Santa Clarita’s suburban streets onto the sprawling freeways or scenic byways beyond, you now have the essential knowledge to make the trip informed and enjoyable. Stay safe out there, and enjoy the ride on California’s highways and backroads alike.  The post All You Need to Know About California Roads  appeared first on Santa Clarita Valley Signal. ...read more read less
