The Oklahoma Highway Patrol says ordnance inspectors with the military have determined that explosives carried on a tractor-trailer that crashed near Hugo in southeastern Oklahoma are stable and are not a danger.
OHP Lt. John Vincent said the military grade explosives were being taken to the McAlester Army Ammunition Plant in McAlester, when the semi and another vehicle collided on US 271 about 12:20 a.m. Wednesday.
Vincent said the explosives are large shells and some spilled onto the roadway. He said southbound lanes of the highway were reopening, but northbound lanes will remain closed while the scene is cleared.
According to the OHP, the semi was crossing US 271 going east, attempting to go northbound on the highway. Another car was going southbound on the highway and it struck the semi's back tires.
The driver and a passenger of the semi-truck were not injured. The driver of the other car involved was air-lifted to Plano Medical Hospital in Plano, Texas, suffering from leg injuries. That driver is said to be in stable condition.
