LA 1 Bridge
DOTD operates the LA 1 Bridge in Lafourche and Jefferson Parish going towards Grand Isle. LA 1 Phase 1 was completed between 2006 and 2011. The LA 1 Expressway is an elevated eleven-mile highway and the sole land route from Leeville to Port Fourchon. The bridge is an all-electronic toll road utilizing the GeauxPass tag system and Toll-By-Plate option.
Construction is underway with LA 1 Phase 2 to expand the elevated highway an additional eight miles to Golden Meadow. LA 1 Phase 2 will replace the existing low-lying roadway, often overtopped and damaged during storm events. This expansion will provide a more convenient evacuation route during hurricane and flooding events, a more reliable shipping route, and increased accessibility opportunities for tourism. This project is expected to be completed in 2027 and will be transferred to Lafourche Parish.

Belle Chasse Bridge
The replacement Belle Chasse Bridge on the West Bank of New Orleans is in Plaquemines Parish. The new Belle Chasse Bridge replaces the moveable Belle Chasse Bridge and Belle Chasse Tunnel which are both over 50 years old. The new bridge is an all-electronic toll road that utilizes the existing GeauxPass tag system and Toll-By-Plate option. At its highest point, this bridge is 73’, so boats will travel underneath without the need to lift. Therefore, travelers won’t experience delays to accommodate marine traffic.

Calcasieu River Bridge
The I-10 Calcasieu River Bridge Project will connect the cities of Lake Charles and Westlake. The project length is approximately 9 miles and will replace the current bridge and parts of the interstate, ramps, service roads, and utilities to make the travel corridor more efficient to navigate. The existing bridge was built in the early 1950s and predates the interstate system. It is narrow, lacks shoulders, and has steep approach grades. The average daily number of vehicles, approximately 90,000, traveling the Calcasieu River Bridge section of I-10 exceeds the design capacity of 37,000 vehicles per day. Once completed (expected by 2031), the old bridge will be removed. The new bridge will utilize the existing GeauxPass toll system.
