Facts & Figures

·        In 2001, Congress recognized LA 1 as a “High Priority Corridor”. This recognition was largely based upon the fact that LA 1 is the primary route to the Gulf of Mexico for offshore activities - including emergency response and hurricane recovery.  

·        NOAA estimates that increases in sea level will require the road, if not elevated, to be closed 6% of the time in 2027.  By 2047, that closure rate has been estimated to be 55%.   LA 1 is the sole access point for the vast majority of oil and gas activities operating from Port Fourchon and we cannot let the anticipated closures reduce our response capabilities and efforts to repair the coast. CPRA’s commitment is a significant step to tackling a foreseeable problem in advance of a catastrophe. 

·       The LA 1 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.

·       The LA 1 project is designed with the bridge superstructure clearing the FEMA base flood elevation. The American Association of State Highway Officials Award for Environment was awarded to the LA 1 Project Team for their collaborative work 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. 

·       The corridor also provides access for wetlands and barrier island restoration projects in Lafourche Parish and Grand Isle, including the state’s largest project to date at the Caminada Headland. Reliable and safe access will play a critical role in supporting large-scale restoration projects funded by the RESTORE Act in the Barataria and Terrebonne basins. 

·       The improvements are estimated to eliminate four fatal crashes per year upon completion, and the traveling public can expect a 57 percent reduction in all types of crashes with the construction of 8 foot wide shoulders that allow vehicle crash avoidance and an increased vehicle recovery width.

·        A 2011 Department of Homeland Security study estimates up to a $7.8 billion loss of Gross Domestic Product should the 7.1-mile section of at-grade LA 1 between Golden Meadow and Leeville be impassable for 90 days.
