The Mississippi River near the Kentucky-Tennessee border reopened to southbound barge traffic early Thursday (Feb. 17) after the motor vessel Navigator sank Tuesday night and backed up barge traffic, the U.S. Coast Guard said. About 20 southbound tows were awaiting passage when the river was reopened at 8:15 a.m. CST (1415 GMT) Thursday, said Lt. Cmdr. Bruce Fisher, the Coast Guard's chief of port operations in Memphis. "At this point it will take about a day and a half to move that line of vessels," said Fisher. There should be no delay for northbound barges. The river was reopened to northbound traffic Wednesday afternoon and the tows that were awaiting passage had cleared the area by Wednesday night, Fisher said.
