The Council in the State of Louisiana, USA has approved Belle Chasse Bridge and Tunnel Replacement project to be developed on Public-Private Partnership Procurement mode.

Belle Chasse Highway (LA 23) is approximately 1.4 miles from LA 3017 to LA 406. The corridor is four lanes with a divided section (raised medium) except at the bridge and tunnel. The movable bridge in Plaquemines Parish was constructed in 1967 and the tunnel in 1955. The LA 23 corridor has a current traffic volume in excess of 33,000 vehicles per day. The goal of the project is to replace the tunnel and bridge with a new mid-level, fixed-span bridge, which would carry traffic in both directions and reduce or eliminate the delays associated with operations and maintenance of the older infrastructure.

Consortium Plenary Infrastructure Belle Chasse (Plenary group, Massman construction and Traylor Bros) will oversee construction, maintenance and operations for the project.

The concession period for the project is 30 years.
