From mid-April to today, some 1600 m3 of high-performance cement composite (CFUP) have been used to reinforce the deck of the Riddes Viaduct.

This quantity has made it possible to reinforce and protect 22,000 m2 of deck, i.e. the running slab and locally the lower slab of the caisson.

The last straight line for the surfacing and equipment works in order to reopen the viaduct to heavy traffic this year-end.
