The $16.4-million project began in February 2005. It 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 expanding areas of Denham Springs and Livingston Parish additional access to and from I-12. 

The Juban Road Interchange at I-12 was delayed because some of the concrete girders had been contaminated with salt water during Hurricane Katrina’s storm surge. Salt water soaked into the girders and damaged the metal strands. If left untreated, oxidation over a 30- to 40-year period could cause corrosion. This corrosion, in turn, could cause cracking and result in pieces of concrete crumbling and falling below the overpass while vehicles passed.

In cooperation with Denton-James, the contractor on the project, DOTD devised an innovative remediation process that cleaned the metal strands and sealed the girders to remove the chance for oxidation. This remediation is ongoing.
