Bourbon Street in the French Quarter of New Orleans is open to cars during the daytime in a one-way direction from Canal Street towards Esplanade Avenue.
At night, from around 7 pm, bollards and police barriers close off most of Bourbon Street to traffic and it becomes a pedestrian mall for night-time revellers. Cross streets remain open to vehicles.
Bourbon Street is also closed to traffic during special events such as New Year’s Eve celebrations and Mardi Gras.
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.
