The work involves the redevelopment of two existing T-shaped crossroads into a traffic light crossroads (RN 94 / avenue de Barbot) and a roundabout (Fanton crossroads). These developments integrate the orientations of urban planning, in particular with regard to soft modes (cycle track, pedestrian crossings and pedestrian sidewalks).

The work involves the redevelopment of two existing T-shaped crossroads into a traffic light crossroads (RN 94 / avenue de Barbot) and a roundabout (Fanton crossroads). These developments integrate the orientations of urban planning, in particular with regard to soft modes (cycle lane, pedestrian crossings and pedestrian sidewalks). This work concerns in particular:

- construction of earthworks, drainage and subgrade;

- the implementation of layers of roadways, including for cycle paths;

- the implementation of sidewalks;

- the making of two reinforced concrete retaining walls including the load-bearing tests of the excavation bottom;

- supply and installation of vertical directional and police signage;

- the supply and installation of horizontal signs including for pedestrian crossings;

- the implementation of a “mountain wall” type retaining device on the bank of the RN 94;

- supply and installation of traffic lights including networks and ancillary equipment (detection loops) and performance of tests;

- taking into account the presence of dealer networks;

- relocation of the Grand Canal from the city of Briançon to the right of the retaining wall to be built at the corner of rue du Chemin de la Tour, including connection to the existing network;

- the supply, installation, maintenance and removal of marking devices and site protection.
