I. Golden Meadow to Port Fourchon (15.1 miles):

Proposed Highway Improvements [ Click image for larger picture ]

A new four-lane, fully access controlled, elevated highway between Golden Meadow and Fourchon, Louisiana (Highway 3090), including interchanges. This section of highway will be elevated above the 500-year base flood elevation, and will be built as two separate 43-foot-wide spans.



II. Leeville Bridge (4.4 miles):

Fixed-span, two-lane bridge with a 300-foot horizontal and 73-foot vertical clearance over Bayou Lafourche and Boudreaux Canal at Leeville. Distance includes interchanges and connector roads.



III. Larose to U.S. 90
(19.5 miles):

A four-lane at-grade highway from Larose to Valentine, including fixed-structure overpasses over the Intracoastal Waterway at Larose and over Bayou Lafourche at Valentine. A four-lane, at-grade highway from Valentine to U.S. 90. Two alternate routes were considered; Alternate 1 was deemed to have the least environmental impact, while still providing access to a proposed evacuation route north of U.S. 90 to Interstate 10.



IV. Port Fourchon to Grand Isle (8 miles):

Highway upgrades and widening of existing two-lane highway.

Total Distance: 47 miles

The LA 1 project is to be designed so that it can be constructed using "end-on" type construction methods whenever possible to protect our sensitive wetlands and marshes. Phased construction will allow the portions of the project to be constructed as funding is available.
