New Champlain Bridge - Support Towers

Signature on the Saint Lawrence (SSL) awarded a contract to Supermétal for fabricating 8 towers. The lattice towers are composed of large 32" diameter tubes and long built-up welded members, over a height of nearly
40m.

​

Montreal’s Champlain Bridge is one of North America’s busiest spans, with 50 million cars, buses and trucks crossing it each year. 

In addition to its being used by residents of the metropolitan region for their everyday commute, the crossing is part of a vital overland link for freight transportation between Canada and the United States.

 

Increased traffic combined with the damage caused by road salt and other factors have contributed to the structure’s considerable wear and tear. This is why, in 2015, a new worksite was put into operation to build the new Champlain Bridge, slated to be completed by December 2018.

​

Designing the new Champlain Bridge is a long-term project that started years before the initial groundbreaking. Here is a brief overview:

 

The project includes:

• The construction of the new 3.4-kilometre Champlain Bridge;

• A new 470-metre bridge for L’Île-des-Sœurs;

• The widening of Highway 15 between the Atwater interchange and the new bridge;

• The improvement of the ramps leading from Highways 132 and 10 on the South Shore to the bridge.
