Video: Crossing the Rivière des Prairies in the Chamouchouane project

Welcome to the jobsite!

Kevin Tétreault invites us to the Rivière des Prairies crossing, where some impressive work is underway in fall 2017.

Félix Sauvé and Jean-Philippe Chouinard explain how construction began with cofferdams to allow towers to be erected in the river. The final step was unreeling the massive power lines.
