Two big rigs - one carrying fresh produce and the other hauling frozen foods - collided on Interstate 81 near the I-70 interchange late Tuesday, injuring both drivers and tying up all southbound lanes for more than six hours.
Maryland State Police reopened one southbound lane around 6 a.m. Wednesday. Both lanes were reopened by 11:30 a.m.
At 11:40 p.m., police called to the scene found that a 1993 International tractor-trailer that had been northbound on I-81 may have had a left front tire failure.
The truck entered the median, partially separating from its trailer which overturned, witnesses told police. The truck continued into the southbound lanes and hit a 1996 Volvo tractor-trailer, causing it to overturn and spill its load of produce.
The driver of the International, James Travers, 28, of Madison Heights, Va., was partially thrown through the windshield. He wasn't wearing a seat belt, police said.
