The Lake Pontchartrain Causeway bascule drawbridge is manned 24/7. Drawbridge operators may be reached on VHF-16 , the marine radio hailing and distress frequency, or by telephone at (504) 836-5442.

To schedule an opening at other times, please contact us at least three hours prior to your desired opening time.
The majority of Causeway spans are about 10’ above the average lake water level. The drawbridge is located at the 16.0 mile marker on the Causeway Bridge (8 miles from the Northshore), and when closed, provides a 45’ clearance for vessels. A fixed high rise is located at the 8.0 mile marker on the Causeway Bridge (8 miles from the Southshore) and provides a 50’ clearance for vessels. Three low rises are located at the 4 mile marker, 12 mile marker, and the 20 mile marker on the Causeway Bridge and provide 25’ clearance for vessels.
The GNOEC operates a Vessel Traffic Service on Lake Pontchartrain. Commercial vessels should contact our drawbridge via radio when entering Lake Pontchartrain and are tracked on radar while traversing the lake. There is a one mile prohibited zone for large vessels on both the east and west sides of the Causeway Bridge for its entire length. Large vessels must obtain prior permission to operate or work within the prohibited zone.
