DOTD announces plan for $3.7 billion in cost savings for continued development of I-49 South

The Louisiana Department of Transportation and Development has announced the continued development of I-49 South will result in $3.7 billion in cost savings.

In its efforts to move forward on I-49 South, DOTD recently completed a study that analyzed the corridor from Raceland to the Westbank Expressway and from Wax Lake Outlet to Berwick. The study helped find improvements and efficiencies to lower costs and re-evaluated the concept for converting U.S. 90 to an interstate facility.

The I-49 South project will convert 160 miles of U.S. 90 from Lafayette to New Orleans into an interstate-quality roadway enhancing travel between the two cities but ultimately across the state and nation once completed.

In addition to completion of the interstate, the revised plan has identified a 15-project interim improvement program for safety and efficiency that can be accomplished independently of interstate construction. The interim program consists of generally lower cost local improvement projects that could be implemented in the near term at an estimated cost of $164 million.

Details of the revised plans for the I-49 South corridor from Raceland to the Westbank Expressway and from Wax Lake Outlet to Berwick will be further evaluated through Supplemental Environmental Impact Statements (SEIS) as part of the NEPA process (National Environmental Policy Act). The SEIS process is expected to begin in 2014 and will include public outreach by DOTD.
