Nearly 100 boats and barges were waiting for passage Monday along an 11-mile stretch of the Mississippi River that has been closed due to low water levels, the U.S. Coast Guard said.
New Orleans-based Coast Guard spokesman Ryan Tippets said the stretch of river near Greenville, Miss., has been closed intermittently since Aug. 11, when a vessel ran aground.
Tippets said the area is currently being surveyed for dredging and a Coast Guard boat is replacing eight navigation markers. He says 40 northbound vessels and 57 southbound vessels were stranded and waiting for passage Monday afternoon.
