A wooden bridge collapsed Saturday night, killing a teen-ager in the second bridge accident in Tennessee this month, authorities said.

Two passengers in the pickup truck were seriously injured in the collapse that occurred as the truck was trying to cross the bridge, which carried traffic over a railroad track, said Sgt. Thomas Mallory of the Tennessee Highway Patrol.A 25-foot section of the 15-foot-wide bridge buckled, he said. Authorities did not say if the truck struck the bridge first.

The bridge is near Oliver Springs in eastern Tennessee.

The victim was identified as Wesley Gallaher, 16. Gallaher's brothers, ages 14 and 16, were in serious condition Saturday night at Oak Ridge's Methodist Medical Center, a hospital nursing supervisor said.

The re-evaluation of the state's bridge inspection program was ordered following the April 1 collapse of a bridge over the Hatchie River near Memphis that sent eight people plunging to their deaths.
