Police stated that the tractor-trailer was traveling in the westbound managed lanes of Loop 820 and then took the Iron Horse Drive exit. For some unknown reason, the driver failed to control his speed. He hit the wall on the other side of the overpass. The cab of the truck crashed through the wall and then fell onto the managed lanes below.

Lt. Jeff Garner said that the driver “showed no sign of breaking at all.” Officials are trying to determine if the incident was the result of an inattentive driver, a medical issue, or some sort of mechanical problem with the vehicle. Garner added that there has been at least two other crashes at this interchange since it opened.

The trailer remain lodged at the top of the overpass for several hours until wreckers could get it pried away.

The fire department’s heavy-duty rescue team had to free the driver from the wreckage. He was taken by air ambulance to JPS Hospital in Fort Worth, where he remains in critical condition. His injuries are not thought to be life threatening, Garner said Monday morning.
