PITTSBURGH (AP) — More than two dozen river barges broke loose from their moorings and floated down the Ohio River in Pittsburgh, striking one bridge that had already been preemptively closed and damaging a marina, officials said. The boats eventually were pinned to the riverbank or went over a dam downstream, officials said.

Pittsburgh police, fire and emergency medical services responded around 11:25 p.m. Friday to reports of the barges “floating uncontrolled” down the river, Pittsburgh Public Safety said in a statement. The area had been hit by flooding after heavy rains Thursday.

The Sewickley Bridge was struck by a barge a few minutes before 2 p.m. Saturday, the Pennsylvania Department of Transportation said. It “was closed in advance of the strike and will remain closed until our crews complete an inspection,” spokesperson Steve Cowan said.
