Lake Charles has officially started tearing into one of Southwest Louisiana’s worst traffic headaches, breaking ground this week on a new Interstate 10 bridge over the Calcasieu River. The multi billion dollar effort will replace the aging 1950s span and overhaul roughly 5.5 miles of I 10, with Governor Jeff Landry and a lineup of federal and local officials on hand as contractors geared up for major construction. State leaders are billing the job as one of the largest transportation investments in Louisiana history.
According to LA DOTD, the $2.3 billion project will take out the existing bridge, add a travel lane in each direction and revamp about 5.5 miles of I 10. The plan also includes a new elevated Sampson Street interchange, an eastbound service road and a dedicated maintenance term that runs for 50 years.
What’s Being Built
Project documents show the new bridge will rise just north of the current span and carry three 12 foot travel lanes in each direction, plus an auxiliary lane and full shoulders. All electronic tolling is planned to keep traffic moving. As laid out on the project website, the design lowers the bridge’s vertical profile and sets aside a $10 million allowance for pedestrian and bicycle facilities.
Funding, Partners and the Price Tag
The work is being delivered through a long term public private partnership led by ACCIONA, Sacyr and Plenary, which will design, build, finance and maintain the corridor under a 50 year concession, according to ACCIONA. While state materials peg construction at about $2.3 billion, the consortium describes the concession as a $3.37 billion long term investment, a difference partners say reflects financing and operations over the life of the deal.
Federal Presence and Local Reaction
Federal Highway Administrator Sean McMaster joined the ceremony in Lake Charles and praised the bridge replacement as part of a broader federal push to speed up major bridge projects, officials said. Governor Jeff Landry called the groundbreaking a milestone for his administration, saying, “This bridge has been a promise of the Landry Administration since day one and I am proud to fulfill it today,” in a statement posted by LA DOTD. The event and portions of leaders’ remarks also surfaced in a U.S. Department of Transportation video post and were covered in local reporting by Louisiana Radio Network.
What To Watch Next
The project has shifted from permitting to active construction work this spring, with the project website and partner materials pointing to an anticipated opening around 2031, followed by tolling once the new crossing is in service. Project partners say construction activity could support more than 16,000 jobs and generate over $1 billion in local economic impact. In the meantime, residents and local officials are expected to keep a close eye on interim traffic management and how toll rates are set as work ramps up.
