The U.S. Coast Guard has reopened the Ohio River in Pittsburgh to maritime traffic, nearly four days after 26 barges broke loose and floated away during flooding. The Coast Guard had barred vessels from a stretch of the river north of the city after dozens of barges got loose from their moorings late Friday, striking a bridge and smashing into a pair of marinas. One of the barges sank and was located by sonar Tuesday. The barge operator, Campbell Transportation Company Inc., has begun work to salvage the other barges. There were no injuries.
