Semi carrying munitions crashes on I-40 in Okla.

A tractor trailer rig carrying explosives from the McAlester Army Ammunition Plant in McAlester has crashed on Interstate 40 in Oklahoma City.

Deputy Fire Chief Cecil Clay says 28,000 pounds of military ordnance are on the rig and officials are waiting for the military to authorize that the load can be checked. He said there were no major injuries.

Westbound lanes of the interstate are shut down just past the interchange with I-35 and traffic is being diverted onto I-35 northbound.

Oklahoma Highway Patrol Capt. Chris West said the semi is owned by Chalich Trucking. A man who answered the phone for the trucking company would not confirm or deny that its truck was involved in the accident and hung up.

The company’s website says it’s based in Ramsey, Mn.
