UPDATE: Northbound lanes at US 281 are still closed at Hildebrand. The closure could last for several hours.
An 18 wheeler lost control and hit the median before colliding with two light poles, according to SAPD officer Doug Greene.
One of the light poles struck a pick up truck though no injuries have been reported.
Slick conditions appear to be a factor in the accident and signage over 281 was damaged in the resulting fire.
Police are expecting the clean up to take several hours and advise motorists to take the long way.
“Utilize the loops,” Green said, referring to loop 410 and 1604.
Vehicles traveling along Highway 281 near Hildebrand are asked to use caution due to a fiery rollover crash involving what appears to be a big rig.
There are currently no reported injuries.
The fire has spread to both north and southbound lanes.
This story is developing.

Officers and SAFD are currently working a major accident involving an overturned 18-wheeler on fire at Hwy 281 SB and Hildebrand. Both NB and SB lanes of 281 are being diverted to the Hildebrand exits. Closures expected for several hours. pic.twitter.com/3iZSsiRCY7
A woman who witnessed the crash told KSAT she was driving directly behind a vehicle that crashed into the guardrail.
She said she immediately called 911 and watched three men, whom she identified as plumbers on their way to work, step into action and break the window to pull the driver to safety.
"They saved his life. By the time fire/police had arrived the vehicle was fully involved. If it weren’t for those men he would have burned to death," she said.
San Antonio Police Department confirmed that a "good Samaritan broke the window and pulled the driver of the 18-wheeler out of the window before the truck was fully engulfed."
