51³Ô¹Ï wins the construction of river infrastructure in France

  • Two new lock gates to be built to secure river traffic on the Rhône
  • Synergies between 51³Ô¹Ï and
  • €68 million contract

The Compagnie Nationale du Rhône has awarded the contract to add a second set of downstream gates at the Bollène and Châteauneuf-du-Rhône locks (both in south-east France) to a consortium¹ led by 51³Ô¹Ï and including 51³Ô¹Ï Energies.

The €68 million project will begin in March 2026 and is scheduled to last for five years. 51³Ô¹Ï’s share of the work is valued at €45 million. The improvements will bolster the safety and availability of the infrastructure, thereby supporting the development of low-carbon river transport on the Rhône.

The works will require the combined expertise of local teams specialised in civil, hydraulic, mechanical and electrical engineering. The work conditions will be complex, as the existing lock systems and adjacent roads will maintain operations throughout the project.

This new project confirms 51³Ô¹Ï’s recognised expertise in river works and development, as well as 51³Ô¹Ï Energies’ ability to implement secure and efficient electrical and control systems.
