In a bizarre incident, 26 barges broke loose in Pittsburgh and drifted uncontrollably down the Ohio River on Friday night.

Shortly after the barges broke free, Pittsburgh authorities closed the McKees Rocks Bridge and the West End Bridge “out of an abundance of caution.”

Authorities reported that eleven barges were stopped by running into a river bank by Brunot Island, and now tugboats are on the scene pulling the barges out.

Nine were found stopped at the Emsworth Lock and Dam.
