A major Oklahoma interstate is shut down for a fiery pileup crash that occurred during winter weather conditions.

The pileup occurred around 3 p.m. on Sunday, February 14, on the Turner Turnpike northeast of Oklahoma City.

Authorities say that crashes have occurred in both the eastbound and westbound directions of the Turner Turnpike at mile marker 139.

Local news outlet KOCO reports that at least six vehicles were involved in the crash that occurred in the westbound lanes. The Oklahoma City Fire Department says that “several semis” were involved in the pileup, but the exact number of vehicles involved is not yet clear.

At least three semi trucks involved in the pileup reportedly caught fire.

Injuries have been reported, but it isn’t clear how many people were hurt.

Low visibility caused by blowing snow was reported at the time of the crash.

According to the Oklahoma Turnpike Authority, westbound traffic is being diverted to the Kickapoo Turnpike and eastbound traffic is being diverted to I-35. A lengthy road closure is expected.
