Phase 1: $371.6 million
Phase 1 construction began in March 2006 and was completed in December 2011.
Phase I of the LA 1 Improvements project includes the development and construction of a fully-access controlled, elevated toll highway on a new location. This toll-financed project located in the State of Louisiana, consists of a two-lane bridge over Bayou Lafourche with interchanges and connection roads immediately north and south of Leeville and includes a two-lane bridge from Leeville South to Port Fourchon on a location that parallels Louisiana Highway 1.
The existing LA 1 required replacement because of subsidence, erosion, and frequent storm damage. In the event of hurricanes, LA 1 is the only highway evacuation route for Port Fourchon and Grande Isle, both of which suffered extensive damage from Hurricanes Katrina and Rita in 2005.
The project was constructed in phases:
- Phase 1A: Fourchon to Leeville Bridge - Approximately 7 miles, 40-foot wide, two-lane elevated highway south of Leeville Bridge to LA 3090 in Port Fourchon. (Open to traffic)
- Phase 1B: Leeville Bridge Approaches and Connector - Two-lane interchanges and connector roads north and south of the Leeville Bridge. (Open to traffic)
- Phase 1C: Leeville Bridge Replacement - Two-lane, fixed-span, high-level bridge (Tomey J. Doucet Bridge) over Bayou Lafourche. (Open to traffic)
- Phase 1D: Customer service center, kiosk network, open-road tolling equipment and intelligent transportation systems (ITS). (Completed)

Refinanced Direct Loan: $122 million

The project is designed so that major portions can be constructed using "end-on-end" construction methods to protect sensitive wetlands and marshes. A movable truss and crane system obviates the need for conventional temporary haul roads and construction pads.
