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 2 phases, 1B and 1C, are now opened to traffic; the existing movable bridge is being removed.

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 interchanges located north and south of Leeville Bridge connecting relocated
  LA 1 with existing road
• Two at grade interchanges at LA 3235, and LA 3090, the project termini
• Toll Customer Service Center, kiosk network and open-road tolling equipment
