Spanning more than 7 km, this construction project involves building a third lane in the westbound direction within the central median. The work includes the creation of a new 3 km traffic lane using both new and recycled aggregates, along with a two-layer asphalt paving process. 

The project also encompasses:

• the installation of 14 high-mast lighting poles
• the construction of two detour roads
• the installation of fibre optic cables through directional drilling
• lane marking. 

Close collaboration between our on-site teams, the St-Jean-Chrysostome quarry, and our quality control department is essential to the project’s success.
