Oklahoma Highway Patrol is on the scene of a crash involving a semi Wednesday afternoon.

Westbound lanes are blocked on the Will Rogers Turnpike at the 302 mile marker, OHP said.

Traffic is being diverted off at the Afton gate and tolls are currently suspended, OHP said.

Drivers can detour on US-60 to rejoin the turnpike at Vinita, OHP said.

This is a developing story.
