AUSTIN (KXAN) -- Part of the northbound side of Interstate 35 in far south Austin was closed early Tuesday morning after an 18-wheeler stalled out and started spilling fuel onto the road. Live Traffic Map The Austin Police Department said shortly before 7 a.m. several of its units responded to the 12000 block of south IH 35 northbound, where a commercial vehicle was stalled and leaking fuel. That's near the Onion Creek area. The interstate reopened around 8:20 a.m. That 18-wheeler crashed into a barrier on the side of the interstate.
