( CNN ) -- Two tank barges loaded with light crude oil struck a bridge in the Mississippi River early Sunday morning . The Coast Guard said it was trying to determine how many gallons may have been spilled into the river near Vicksburg , Mississippi . The tank that was leaking contained 80,000 gallons of oil . A Coast Guard team has stopped the source of the spill , the agency said in a news release . The river is closed from mile marker 425 to 441 . No one was injured in the accident , which happened at 1:30 a.m . The Mississippi River at Vicksburg moves about 890,000 cubic feet of water per second , according to the U.S. Geological Survey . If the vessel were to lose all its oil , that would be about 11,000 cubic feet . In February 2012 a tanker barge spilled 10,000 gallons of oil into the Mississippi after a collision near New Orleans . The Coast Guard drained the barge and towed it to a repair facility .
