Deep in the hills of southern France, a team of 2,000 workers is building one of Europe's most ambitious engineering projects: the Valmore Bridge. When complete, the bridge will span 380 metres across a wide, forested valley, connecting two communities that have waited decades for a direct road link. But completion is still some way off — and the team has a demanding schedule ahead.
By the end of this year, engineers will have completed the two main towers, each standing 180 metres high. These towers are the backbone of the entire structure. By March of next year, the main suspension cables will have been installed, stretching between the towers and anchoring into the hillside on either side of the valley.
By the end of next year, workers will have laid more than 45,000 tonnes of concrete across the bridge deck. By June in two years, the road surface will have been finished and safety barriers will have been installed along the full length of the bridge.
The final months before opening will involve intensive checking. By September in two years, the project team will have spent over €800 million on the construction. Inspectors will have carried out more than 4,000 individual safety checks to ensure the structure meets European standards.
The project manager, Sofia Leclercq, is proud of what the team has achieved. 'By the time we open this bridge to traffic, it will have taken seven years to build,' she says. 'When we cut that ribbon, we will have achieved something remarkable. Future generations will cross this valley in minutes — a journey that used to take nearly an hour. That is what engineering is for.'
