Project Description

The LA 1 Improvement Project passed a comprehensive and rigorous Environmental Impact Study process, and the Record of Decision to build the elevated highway is authorized by the U.S. Federal Highway Administration in agreement with the Louisiana Department of Transportation and Development and in cooperation with the U.S. Environmental Protection Agency, the U.S. Army Corps of Engineers, the U.S. Coast Guard, and the National Marine Fisheries Service.

In a thorough and public review, spanning more than three years, all environmental permits were completed in 2004. These documents call for state of the art end-on construction, which nearly eliminates the construction impacts upon wetlands.


The LA 1 Highway Improvement Project includes pre-construction design and engineering, and four phases of highway construction:

Pre-Construction, Phases 1&2 COMPLETED           $ 43,300,000

Phase 1 – (Leeville to Port Fourchon) COMPLETED           $ 318,800,000

Phase 2 – Golden Meadow to Leeville           $ 346,000,000

Phase 3 – U.S. 90 to Larose           $ 340,000,000 est.

Phase 4 – Additional Lanes, Golden Meadow to Fourchon           $ 660,000,000 est.

Louisiana residents and businesses have agreed to pay tolls for the next 30 years to repay a federal transportation loan and bond sales that funded construction of Phase 1 of the LA 1 project. Now, our local financing capability for this nationally critical highway corridor is exhausted.


Construction of Phase 2 of the LA 1 Improvement Project - eight miles of elevated highway between Golden Meadow and the new Tomey Doucet Overpass in Leeville - will be divided into Segments A,B,C, D and E.
