The LA 1 Relocated project will provide an 18-mile, fully access controlled, elevated highway on a new location between Golden Meadow (LA 3235) and Port Fourchon (LA 3090). The project is designed so that major portions can be constructed using “top-down” construction methods to protect our sensitive wetlands and marshes. Phased construction is being used to allow the project to be constructed in segments as funding permits. The first 4 phases, 1A, 1B, 1C, and 1D are now complete and opened to traffic; the old movable bridge over Bayou Lafourche has been removed. Phase 2 is scheduled to be let in the 4th quarter of 2021. The LA 1 Relocated Project includes: Approximately 18 miles of low-level and medium-level bridges Fixed high-level bridge over Bayou Lafourche (Leeville Bridge) with 73 feet vertical opening Channel crossings of navigable Boudreaux and Bollinger Canals Two elevated bridge intersections located north and south of Leeville Bridge connecting relocated LA 1 with existing road Two interchanges at LA 3235, and LA 3090, the project termini Toll Customer Service Center, kiosk network and open-road tolling equipment Project Phasing Phase 1A: Fourchon to Leeville Bridge – Approximately 5 miles, 40-foot wide, two-lane elevated highway south of Leeville Bridge to LA 3090 in Port Fourchon.
