The new $4.2 billion Samuel-de Champlain Bridge is a standalone structure on its own piers, crossing the St. Lawrence River and connecting the Island of Montreal with the south shore. It replaces the original bridge that opened in 1962.

The new bridge also includes a multi-use path for pedestrians and cyclists. It is expected to have a 125-year design life. The Samuel-de Champlain is the busiest bridge in Canada, carrying more than 50 million vehicles a year.

Plate steel for the project was supplied from our plants in Burns Harbor and Coatesville in the US. It is used in the construction of the tub and plate girders, part of the structural section of the bridge, which was fabricated by our customer Canam Bridge, Quebec City, Quebec, with a portion fabricated at its facility in Claremont, New Hampshire. Rebar for the concrete deck portions of the bridge was supplied by ArcelorMittal Contrecoeur, just 63 km north along the St Lawrence River.  

“ArcelorMittal plate was selected because of our ability to make the wide range of grades and sizes required for this project,” said account manager Gary Moffat. “Having worked with Canam on a range of projects over the last 8 years, and with preferred supplier status, we have a great relationship. They know they can rely on us as a partner, not just a supplier.”

Large, high-profile projects such as the Samuel-de Champlain Bridge require a great deal of coordination and commitment on the part of suppliers to get customers their products when they need them.

“Our participation in this project evidences that ArcelorMittal can provide the product, quality and on-time delivery that is essential to the success of a project of this nature. And to our own people, who are involved in the production of the steel, testing, shipping, and getting all the necessary paperwork together, it is a real source of pride that they feel each time they drive over the bridge.”
