The Belle Chasse Bridge and Belle Chasse Tunnel are crucial entry points for the people and businesses in Plaquemines Parish.
Both the bridge, which has been operational since 1968, and the tunnel, built in 1956, are near the end of their expected lifespan. They frequently need repairs, causing disruptions that impact travel for the public.
To address this, a replacement project was approved in 2017 using a Public-Private Partnership (P3), the first of its kind for LADOTD. This approach secured various public funding sources to execute the project and set an example for similar state projects.
To fix the problems caused by old infrastructure, this project replaces the previous draw bridge and tunnel with a new 4-lane bridge. This change will allow safer and more reliable travel throughout Plaquemines Parish.

This project replaces the previous draw 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.
