Stops at the 326.2-m fill section at the south approach.


Extends from Pier 1 to Pier 9.


Spans the St. Lawrence Seaway and is approximately 36.6 m above the canal surface.


Extends from Pier 10 to Pier 19A, which is the southern boundary of the Île Sainte-Hélène Pavilion.


The Île Sainte-Hélène Pavilion is a three-story building. A rare example of Art Deco architecture in Montreal it is being renovated for a new use. It has a pedestrian tunnel decorated with murals that lets people get from one side of the bridge to the other under the traffic lanes.


Extends from the north boundary of the Île Sainte-Hélène Pavilion to Pier 23.


The most recognizable part of the bridge, this cantilever section extends from Pier 23 to Pier 26 and spans the St. Lawrence River. It has two anchor spans at each end, two cantilever spans and a central suspended span. The bridge engineers combined aesthetics and technique to create a remarkable interplay of proportions.

The main span includes the four finials often called the “Eiffel Towers.” From the deck, you would never believe that each one is nearly 4.6 m tall and weighs about 6 tonnes!


Includes a section with steel towers.


North approaches that are partly on concrete arches.


Thanks to intelligent programming, the Jacques Cartier Bridge is the first connected bridge that comes alive every night and changes with the rhythm of Montreal’s seasons and energy.
