How long does it take to drive across Lake Pontchartrain?

Last updated December 24, 2020 by ZagBot 1 Comment

In good daytime conditions, driving across the Lake Pontchartrain Causeway between Metairie and Mandeville, Louisiana, takes approximately 25 minutes.

In foggy conditions, the crossing time will be nearer 45 minutes as traffic is restricted to a single lane and a speed limit of 35 mph.

At the 16 mile marker, the bridge has a bascule drawbridge to allow passage of marine vessels, which requires road traffic to stop when raised.
