GROUNDBREAKING VIDEO – April 12, 2021
The Belle Chasse Bridge and Belle Chasse Tunnel serve as the primary access points for the residents, businesses, and industries of western Plaquemines Parish. Both the bridge and tunnel are located on the LA 23 corridor, which has a current traffic volume in excess of 33,000 vehicles per day.
The movable bridge began operating in 1968 and the tunnel in 1956. These structures are near the end of their design life span. Currently, there is a need to replace unreliable and inefficient infrastructure due to frequent, costly, and unpredictable operations for repair and maintenance which impact the public’s ability to travel.
In 2017, the Louisiana Joint Transportation Committee approved the use of a Public-Private Partnership (P3) to deliver the replacement project. This project is LADOTD’s first P3 and is paving the way for this delivery method to be utilized on other state projects. Several public sources of funding were secured to execute the project.

The project will replace the existing bridge and tunnel with a fixed-span, 4-lane bridge. Replacement of these structures will allow for safer and more reliable access for the residents, businesses, and industries in Plaquemines Parish. Improving the connectivity via this corridor will address the current conditions and operational constraints created by aging infrastructure.
