The US Coast Guard has established a temporary safety zone closing to navigation the Atchafalaya River from Mile Marker 117 (Morgan City Railroad Bridge) to Mile Marker 0 (Simmesport, Louisiana). This action is necessary to protect against destruction, loss, or injury due to hazards associated with rising flood water. The safety zone will be in effect through July 31. 76 Fed. Reg. 35104 (June 16, 2011).
