DOTD I-12 Widening Project

Staff | September 28, 2010

Louisiana Department of Transportation and Development (DOTD) Secretary William D. Ankner has signed a $100-million design-build contract to widen parts of Interstate 12 from four lanes to six lanes before Thanksgiving 2011. The project, which will begin construction in February 2009, is 100-percent funded from surplus state funds that were awarded by Governor Bobby Jindal and the Louisiana Legislature this year. The engineering/construction team, which was chosen through a competitive process, includes James Construction Group, Boh Bros Construction Co., Evans-Graves Engineering, Volkert & Associates, and GOTECH Inc.

Highlights of the project include:

  • Widening the eastbound interstate from two lanes to three lanes with 10-foot shoulders from O'Neal Lane in Baton Rouge to just east of Range Avenue in Denham Springs.
  • Widening the westbound interstate from two lanes to three lanes with 10-foot shoulders from just west of Range Avenue in Denham Springs to O'Neal Lane.
  • Two new side-by-side bridges over the Amite River featuring three lanes each and 10-foot shoulders.
