Government of Canada marks the 90th anniversary of the Jacques Cartier Bridge.


The Jacques Cartier Bridge is a five-lane bridge that connects Montreal to Longueuil. It also has entrance and exit ramps to Île Sainte-Hélène.



The three-lane bridge was opened to traffic on May 14, 1930 and inaugurated on May 24, 1930. On June 23, 1934, the Harbour Commissioners of Montreal adopted a resolution recommending to His Excellency the Governor General in Council that the Harbour Bridge be renamed the “Jacques Cartier Bridge” in homage to the French explorer and in recognition of the 400th anniversary of his arrival in Canada in 1534.

Key dates

From Longueuil, people could take two ferries to Montreal during the summer in 1921. During the winter, motorists could risk crossing an ice bridge during the few weeks of severe cold. The need for a new link between Montreal and the South Shore was becoming more and more urgent. On August 14, 1922 a competition is launched for the bridge site. The Harbour Commissioners of Montreal announce that they have selected the Monsarrat and Pratley of Montreal engineering firms for the project.

1929. Construction of the Jacques Cartier Bridge



1929. Construction of the Jacques Cartier Bridge         –         1930. First operating year of the Jacques Cartier Bridge



Started in 1925,the bridge construction took four years. The work was done so quickly that the contractors delivered the bridge in December 1929 instead of May 1931, or nearly a year and a half earlier than expected.

The construction cost was approximately $23 million (1929), including expropriation expenses and the approaches on the fill sections.


Over the past 20 years, major repairs have been preserved the structure’s integrity and ensured that the bridge remains safe.
