Four people were killed when two 18-wheelers and other cars collided tonight on the Pharr-Reynosa International Bridge that spans the border between Texas and Mexico. Pharr police Lieutenant Lupe Salinas tells The Associated Press three of the dead were in a pickup truck that fell off the bridge and landed on a road below.

Salinas says the other victim was in another vehicle that collided with the tractor trailers on the American side of the crossing.

He says the trucks had been traveling on opposite directions on the bridge.

Pharr Emergency Management Coordinator Elsa Sanchez says the pickup truck that fell from the bridge had Texas license plates.

Both 18-wheelers and a minivan involved in the wreck appeared to have Mexican license plates.

Assistant bridge director Fred Brouwen says the wreck caused no damage to the structure of the bridge.

The bridge is typically closed from midnight to 6 a.m. Brouwen said he didn’t expect the bridge to reopen until 6 a.m. this morning.
