Pittsburgh officials say multiple bridges are now reopened after barges got loose and began floating down the Monongahela River.
The incident shut down the Liberty, Smithfield, Fort Pitt, West End and McKees Rocks bridges. The DOT says in a tweet all four bridges were reopened as of 9 a.m.
Bridge inspection crews were dispatched to determine if any of the spans were damaged by the runaway barges.
Officials are urging drivers to avoid the affected areas due to heavy traffic.
