Proud to announce the successful first phase of RTE’s Chevalet project, which was completed this week in northern France. The 130-metre-long, 1.5 metre wide microtunnel, carried out by EIFFAGE GENIE CIVIL RESEAUX, crosses under the A1 motorway as well as the high-speed Paris – Lille railway link.
The Chevalet project, part of France’s renewable energy development programme, called for in-depth geotechnical analysis and engineering design, which was carried out by OPTIMUM from 2020 to 2022 in collaboration with RTE’s project team. OPTIMUM also accompanied RTE during the contractor selection phase and monitored the construction work, which took place between January and April 2024, ensuring all environmental, technical and regulatory constraints were respected.
This careful preparation and close supervision ensured that road and rail traffic as well as infrastructure were unaffected throughout the construction of the microtunnel.
Thank-you to RTE for its confidence and to everyone involved for their professionalism. It’s great to contribute to the success of these strategic French / European electricity network projects.
