Calcasieu River Bridge, a huge P3 project in the U.S.

We are members of Calcasieu Bridge Partners (CBP), the consortium entrusted with building the new Calcasieu Bridge on the I-10 in the State of Louisiana, which will replace the current bridge, dating back to the 1950s. This is our first infrastructure P3 project in the U.S.

We improve local and interstate connectivity in Louisiana with a new bridge over Calcasieu River at the Interstate 10, which will replace the current bridge, built in the 1950s.

This Louisiana Department of Transportation and Development (LA DOTD) project comprises the design, construction, finance, operation, and maintenance of this 5.5-mile (9 km) infrastructure for a 50-year term.

Contract calls for a $2.1 billion expected investment (€ 1.9 billion).

We’ll develop this project as Calcasieu Bridge Partners (CBP), comprising Sacyr, Acciona and Plenary Americas.

This is a highly anticipated project for road users that will meet the highest standards.

This project is the largest to date in the history of the State of Louisiana, and one of the was one of the largest infrastructure contracts commissioned in North America in 2023.

The project

Calcasieu River bridge is our second P3 in this country, and one of our major projects by investment volume and business portfolio.

The Interstate 10 (I-10) P3 in Louisiana is a major road project that will substantially improve the connectivity between the cities of Lake Charles and West Lake, located in the southwest of the State, in the vicinity of the Texan border. This route is also a central connection between the coasts of Florida and California.

A 50% Sacyr-Acciona joint venture will be in charge of constructing the bridge.

Construction works are expected to begin in 2024 and the operation in 2031.

The widening of the I-10 comprises the construction of a six-lane corridor and the implementation of a free flow toll, as well as various structures, ramps and approaches to the bridge.


This solution will incentivize the local economy and become a growth driver for future generations, as it will reduce travel times and enhance road safety for more than 90,000 vehicles per day.
