Rescuers late Tuesday pulled the body of a construction worker from the Brazos River after he and another worker plunged into the river when a boom being used to build a new pedestrian bridge collapsed Tuesday afternoon.

Waco police Sgt. W. Patrick Swanton said two workers were strapped to a boom working on the bridge that will connect the $260 million McLane Stadium to Baylor University’s campus when the boom suddenly fell into the river just after 4 p.m.

One worker was able to unharness himself and was pulled from the water. He was treated for hypothermia at Providence Health Center, Swanton said.

Waco firefighters and state game wardens searched the river Tuesday evening with sonar equipment in an effort to locate the boom and missing worker.

Swanton said divers on a team that came in from Belton “found what is believed to be the body of the missing construction worker,” and the man was pronounced dead at 8:17 p.m.

The worker’s identity was not released, pending notification of relatives and a positive ID on the man.

Swanton said he had no information about the man who was rescued.

Waco police are investigating the incident as an “industrial accident,” Swanton said.

Construction workers at the scene Friday afternoon declined comment as they and Baylor police officers scurried to block off the area just behind Baylor Law School.

Baylor officials deferred comment Tuesday evening to Waco police.

The boom was attached to a crane in the river as workers build a $9.1 million pedestrian bridge over the water.

Jeff Horn, senior superintendent for general contractor Austin Flintco, said last week during a media tour of the new stadium that the project is 60 percent complete.
