Interstate 10-Calcasieu River Bridge Replacement

interim design process

Construction of a new Interstate 10-Calcasieu River bridge in Louisiana, planned to be built in four segments simultaneously. The new bridge will reduce the height from 152 feet to around 75-95 feet for a smoother ride, include enhanced arch-shaped lighting, four towers with replicas of current pistols, three travel lanes each side, shoulders, and auxiliary lanes. The project includes electronic tolling starting August 2031 with discounted rates for local noncommercial vehicles. Traffic is expected to shift to the new bridge in February 2030, followed by demolition of the current bridge. Final acceptance is scheduled for December 2031.
