The US Coast Guard Sector New Orleans issued a Marine Safety Bulletin stating that, beginning in October 2007 and extending through August 2008, the Lower Mississippi River periodically will be closed to navigation at the Huey P. Long Bridge, mile marker 106.2 above Head of Passes, to allow for heavy lift work associated with the widening of the bridge. The closures, occurring once or twice a week, will last either six or twelve hours each, depending upon the nature of that day’s lift. At other times, transits through the area are to be at a slow bell, creating minimum wake. The Coast Guard will regularly publish a two-week closure schedule so that mariners may make appropriate plans. [Source: HK Law]
