Montréal - Reparation of the St-Pierre interchange

Work platforms will be installed between the existing bridge beams to allow bridge repair. This installation will be done manually and does not require the use of any machinery. The work platforms will be completely closed and hermetic.

Repair work will be carried out from above the deck or from inside the platform. No discharge will be made in the channel. All waste management will be done from the bridge or from inside the walkways.

No activity will require access other than the platforms.
