An oversize 18-wheeler slammed into a highway bridge Thursday morning in Salado, Texas, collapsing support beams which fell onto vehicles traveling Interstate 35, killing one person and injuring three others, reports KWTX.

One beam fell on a pickup truck driven by Clark Davis, a 32-year-old Arlington man, who died at the scene, along with a second tractor trailer, which burst into flames.

Nick Delgado with KWTX, who was on the scene, said a pickup truck appeared to be buried beneath the pillars.

"There is a mountain of concrete. There's debris that came out of the back of one of the 18-wheelers just all over," said Delgado.

The injured victims were transported to Baylor Scott & White Hospital in Temple with non-life-threatening injuries, according to authorities.

One person was flown to the hospital by helicopter and two others were driven by ambulance.

Two of the injured victims had been released from the hospital by Thursday afternoon, according to officials.

The third victim was admitted to the hospital and reportedly is in stable condition.

The construction company working on the bridge used a crane to move debris from the roadway to search for more victims.

In total, three 18-wheelers and two pickup trucks were involved in the accident.

The bridge had a 14-foot ½-inch clearance, the Texas Department of Transportation (TxDOT) told KWTX, which is lower than the standard 16 ½-foot clearance on rural interstate highways and 5 ½ inches lower than the minimum 14-foot 6-inch clearance required by TxDOT's own Bridge Project Development Manual, according to KWTX.

TxDOT said that three signs were posted in advance of the bridge warning of a 13-feet 6-inches vertical clearance, which is less than the actual height. The first sign was two miles from the bridge, the second was 1 mile away and the third sign was at the FM 2484 exit.

I-35 was closed for nearly 18 hours after the fiery crash and reopened early Friday morning.

TxDOT plans to lower the lanes of I-35 to allow the normal 16 ½-foot clearance, according to KWTX.
