The A41 motorway

As part of a concession contract, Bouygues Construction and Colas constructed the north section of the A41 motorway. The particularly challenging 3-kilometre Mont Sion tunnel was built in record time thanks to the use of 18,000 voussoirs precast on-site. The motorway means that Annecy is now 30 minutes from Geneva, which is key to the economic growth of the region.
