A truck driver is in serious condition after crashing through a barrier wall at an unusual exit, separating the cab from the trailer and sending it plunging to the highway below.

The accident happened on Sunday, November 12th at approximately 10 p.m. at the intersection of Northeast Loop 820 and Iron Horse Boulevard in North Richland Hills, Texas.

According to NBC DFW, an unidentified truck driver was traveling west on Northeast Loop 820 in the TEXpress lanes when he took the Iron Horse Boulevard exit. As the truck driver climbed the elevated exit, he apparently failed to see the stop lights and drove straight through the intersection at the top of the ramp. The big rig then drove through a protective barrier wall, separating the cab from the trailer and sending it plunging to the highway below.

The trailer was left teetering on the edge of the bridge, spilling a large amount of its cargo of mayonnaise onto the ground below.

The truck driver was seriously injured in the crash and a portion of Northeast Loop 820 had to be closed temporarily to allow for a medical helicopter to land. He was transported to the hospital in serious condition. His current condition has not been released.

One lane of NE Loop westbound remains open as crews work to clear the wreckage from the roadway, and the Iron Horse Boulevard exit ramp has been shut down until the barrier wall can be repaired.
