Progress

Phase 2E construction

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.

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, which was completed in 2011. Now, our local financing capability for this nationally critical highway corridor is exhausted.
