Belle Chasse Bridge and Tunnel Replacement PPP Project in Louisiana

project signed

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. A new mid-level fixed-span bridge is proposed to replace the existing moveable bridge and the tunnel. The project will span the Gulf Intracoastal Waterway on Louisiana Highway 23 in Belle Chasse, Louisiana. To the northwest, LA 23 connects to I-910 in the City of Gretna. To the southeast, LA 23 connects to the Belle Chasse Naval Air Station, the census-designated place known as Belle Chasse, and the Scarsdale Ferry crossing the Mississippi River. The goal 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.
