Built almost entirely underground, the garage includes the construction of 10 parking and maintenance lanes for subway trains. On the surface, three buildings provide access to the garage and allow its operation. The work of the architectural team —STGM / Jodoin Lamarre Pratte / Bisson Fortin architects in consortium— was not limited to this, as they participated in the entire project: technical, work and rest areas; accesses, hardware, wrought-metal structures, all of which are necessary for the proper functioning of the garage.
