A new bridge carrying Interstate 10 is being planned for Calcasieu in Louisiana. The new structure is expected to cost from US$400-600 million to construct and will feature three lanes in either direction, with provision also for cyclists and pedestrians. The bridge will be built to the north of the existing I-10 bridge, which was constructed in 1952 and is no longer able to cope adequately with the traffic volumes it carries. The new bridge is expected to be funded privately, with tolls for drivers crossing the structure. However approval for the project has yet to be given by the local authorities.
