On Wednesday, Louisiana Governor Jeff Landry officially broke ground on the long-awaited I-10 Calcasieu River Bridge Replacement Project. The ceremony marks the official commencement of construction on a multi-billion-dollar Public-Private Partnership (P3) designed to modernize one of the most critical infrastructure corridors in the United States.
The $2.3B project will replace the existing 1950s-era Calcasieu River Bridge with a state-of-the-art structure engineered to meet 21st-century demands. While the new bridge is under construction, the current bridge and its connecting ramps will undergo strategic upgrades to ensure continued service until the new bridge opens in 2031.
The corridor will feature expanded capacity and modern engineering standards, with three travel lanes in each direction addressing the structural and functional limitations of the current bridge. Construction activities will ramp up immediately following today’s ceremony.
Beyond the bridge itself, the comprehensive project includes:
- Reconstruction of 5.5 miles of I-10 to replace aging roadway and multiple other bridges
- Addition of a travel lane on I-10 in each direction to increase capacity and eliminate the existing bottlenecks
- Construction of a new elevated Sampson Street interchange to eliminate railroad crossings and facilitate predictable travel
- Creation of an eastbound service road system between PPG Drive and Sampson Street to reduce congestion and weaving on I-10
- Reconstruction of the I-210 westbound ramp for enhanced safety and capacity
- Inclusion of a $10M Active Transportation allowance to create new facilities for pedestrians and cyclists around the bridge
- Dedicated maintenance of the new roadway and bridge for a 50-year term
“Bringing modernized infrastructure to this heavily traveled section of the Interstate 10 corridor is long overdue,” said Louisiana Department of Transportation and Development Secretary Glenn Ledet. “This is a huge milestone in the department’s ongoing commitment to improving and strengthening transportation throughout the state. The department collaborated with agencies and officials on all levels to make this project a reality.”
This massive undertaking requires unprecedented coordination between local industry, railroads, utility providers, and all levels of government.
“Under the leadership of President Trump and Secretary Sean Duffy, the U.S. Department of Transportation and Federal Highway Administration are enhancing Americans’ freedom to drive by building big, beautiful roads and bridges, and partnering with Louisiana and other states to address congestion and accelerate project delivery,” said Federal Highway Administrator Sean McMaster. “This is exactly what Louisiana is doing as we break ground on the new I-10 Calcasieu River Bridge. I’m thrilled to join our partners to get shovels in the ground for this project and make travel more convenient in Southwest Louisiana.”
The innovative P3 funding model allows for expedited construction timelines and private investment. Notably, the State of Louisiana maintains a 15-percent equity share in the tolling revenues generated by the project, which will provide for continued infrastructure investment in the region.
More than just a local thoroughfare, this corridor is the backbone of the U.S. energy sector. The project guarantees reliable, uninterrupted access for U.S. natural gas and petroleum to reach Gulf ports and supply the global market which is helping ensure the nation’s energy dominance. It is estimated to bring $3.29B in economic impact to the region, create more than 16,000 jobs during the project’s lifecycle, and $1.9 Billion in labor income.
