The bascule drawbridge is managed by the GNOEC (Greater New Orleans Expressway Commission) and is located at the 16.0 mile marker on the Causeway Bridge with personnel on duty 24/7. Drawbridge operators may be reached on VHF-16 , the marine radio hailing and distress frequency, or by telephone at (504) 835-3116. The GNOEC operates a VTS (Vessel Traffic Service) on Lake Pontchartrain. All commercial traffic communicates with drawbridge operators and is plotted and tracked on radar while traversing the lake. There is a one mile prohibited zone on both the east and west sides of the Causeway Bridge for its entire length. Applications for work to be performed within the prohibited zones must be submitted to the GNOEC for approval. 9,000 piles support the bridges.  Piles average 90’ in length.
