Highway 401 – Montreal Street Bridge

Harsh winters are no match for advanced manufacturing of infrastructure products – even when those products are exceptionally large. Construction of the new bridge in Kingston was accelerated thanks to prefabrication of the girders within our 100% controlled, 100% indoor manufacturing facility.

CPCI 2300 girders were specified which generally have a maximum span of 45 m. This bridge construction called for a 47.3 m span across the westbound lanes of the 401, and a 40.8 m span across the eastbound lanes. A total of eighteen girders were supplied by DECAST. The girders had to be specially designed for transport to ensure stability and maintain girder quality.
