Denham Springs, La. – The Louisiana Department of Transportation and Development (LA DOTD) has opened the $16.4 million Juban Road Interchange at Interstate 12. Concrete girders fabricated for the project and stored in a Gulf Coast facility were contaminated with salt water during Hurricane Katrina’s storm surge, which caused delays for the project. Salt water soaked into the girders and damaged the metal strands.
Denton-James, the contractor on the project, and LA DOTD devised an ongoing remediation process to clean the metal strands and seal the girders, removing the chance for oxidation. The project began in February 2005 and includes a new five-lane overpass with a center turning lane and on- and off-ramps to I-12 eastbound and westbound. The overpass and interchange will help with congestion at Range Road and give the areas of Denham Springs and Livingston Parish additional access to and from I-12.
