The work undertaken was in connection with access routes to the resorts of CHAMROUSSE, where the Alpine events took place, AUTRANS, VILLARD-DELANS, SAINT-NIZIER, the centres for the crosscountry, jumping and toboggan events, and ALPE D'HUEZ where the bobsleigh races took place. The works involved the widening of the road into two one-way lanes, each from 7 to 9 metres wide.
