HAMPTON, Va. (WAVY) -- Cooking oil that spilled from a truck traveling through the eastbound tube of the Hampton Roads Bridge-Tunnel Friday morning caused lane closures. 10 On Your Side was first alerted about the incident around 5:30 a.m. Courtesy: Matt Conway Courtesy: Matt Conway Courtesy: Matt Conway Courtesy: Matt Conway All HRBT eastbound lanes in Hampton were closed, and the west lanes had to open periodically to allow some traffic through. All lanes have since been reopened. Traffic backups were more than five miles during the closure. There was a detour in place at exit 267. Even with lanes reopened, delays are expected through a large portion of the morning. Meanwhile, there were also delays at the Monitor Merrimac Memorial Bridge-Tunnel on I-664, which is an alternate route to the HRBT, because of a disabled tractor-trailer. That incident was in the city of Newport News, near 26th Street, according to VDOT. Save time on your drive by getting WAVY alerts on crashes, delays and detours.
