Preparatory work: First worksite done!

Work being done near the future Villanelle auxiliary structure mainly consists of relocating urban public utilities (underground cabling and a Hydro-Québec utility pole). We will then have free rein to begin the massive excavation that will be needed to build the new infrastructure.

Here are some photos of the work we’ve done:


We relocated a Hydro-Québec utility pole, freeing up the space needed to build the new infrastructure on the southwest side of the intersection.

We also dug trenches to install cabling underneath the street that will be protected by red conduits. The cables will connect to the new electric utility pole.

We then poured concrete over the new conduits and ran the cabling through them, moving it from the other side of the street where it was in the way of building the new auxiliary structure.

Get involved

An auxiliary structure is a service building, closed to the public and located between two métro stations, that houses a variety of mechanical and electrical equipment needed for métro operations. This includes ventilation equipment, power supply infrastructure and pumps to remove runoff water. There are currently hundreds of these buildings in the métro network.
