Presently, the draws are required to open on signal if at least three hours notice is given.

SUPPLEMENTARY INFORMATION:

During the closure period, the bridges will not be able to open for vessels to transit through the bascule spans of the bridge. The bridges have a vertical clearance of 42 feet above mean high water in the closed-to-navigation position. Navigation on the waterway consists of small tugs with tows, fishing vessels, sailing vessels, and other recreational craft. In case of an emergency, the bridge owner will be able to hand crank the draws of the bridges to the open to navigation position. As an alternate route, the south channel fixed spans of the dual bridges provides a vertical clearance of 50 feet above mean high water.

The Greater New Orleans Expressway Commission requested a temporary deviation from the normal operation of the drawbridge in order to allow for the connection of new submarine cables to operate the draw spans of the bridges.
