Installation of four overpasses on the A41 highway

As part of the development work on the A41 motorway for the creation of a 2 x 3-lane crossing between the interchange north of Annecy and the Saint-Martin-Bellevue tollgate, Matière® is involved in the realization, the studies, the manufacture and the assembly by crane of four overpasses.

 

The manufacture of the structures is carried out within the factories of Charmes and Ocquier. The Belgian subsidiary MBB acts as subcontractor in the manufacture of two overpasses.

 

This major axis of 6 km is the busiest of the A41 between Chambery and Geneva, with more than 50,000 vehicles running daily on this section. The aim of this work is to relieve this problem, improve fluidity and enhance safety.

 

This vast project will therefore cause major disturbances for a minimum of 30 months for all users of the highway, the speed will be reduced to 90 km / h on the 2 lanes of traffic during the duration of the work.
