The Jacques Cartier Bridge (French: pont Jacques-Cartier) is a steel truss cantilever bridge crossing the Saint Lawrence River from Montreal Island, Montreal, Quebec to the south shore at Longueuil, Quebec, Canada. The bridge crosses Île Sainte-Hélène in the centre of the river, where offramps allow access to the Parc Jean-Drapeau and La Ronde amusement park.
The five-lane highway bridge is 3,425.6 m (11,239 ft) in length, including the approach viaducts. There are approximately 35.8 million vehicle crossings annually, making it the third busiest bridge in Canada, the first being Champlain Bridge, just a few kilometres upstream. The second busiest bridge in Canada overall is the Port Mann Bridge in Metro Vancouver (connecting Surrey to Coquitlam).
Discussions began as early as 1874 about the construction of a new bridge to alleviate the congestion on Victoria Bridge, which was then a rail-only bridge, the wintertime ice bridge and the ferries used to connect the city to its south shore. The decision to build the bridge was made official in 1924. The bridge was designed by engineer Philip Louis Pratley.
Construction was undertaken by the Dominion Bridge Company starting in 1925. On August 9, 1926 the cornerstone was laid, integrated into the pillar at the corner of Notre Dame Street and Saint Antoine Street, opposite the Pied-du-Courant Prison. The cornerstone contains a capsule with 59 items reflecting the year in which construction began. The bridge was constructed of steel at a cost of C$23 million, and the work lasted two and a half years.
The groundbreaking was held on May 26, 1925. Construction began immediately and the cornerstone was laid on August 9, 1926 on Pillar No. 26. The superstructure was built between September 1926 and September 1929. 33,267 tons of steel were needed for its construction. The work was completed about a year and a half ahead of schedule, without disrupting river traffic.
It opened to traffic on May 14, 1930, however the inauguration ceremony took place a few days later, on May 24. The bridge was inaugurated as the "Harbour Bridge" but was renamed "Jacques Cartier Bridge" in 1934, following a petition from citizens to honor the explorer who discovered Canada in 1534.
The bridge was originally designed as a road, tramway, and pedestrian bridge. The original bridge had three lanes of road traffic and two sidewalks. Space in each direction was left free for the possible installation of two tramway lines. Tramway tracks were installed but never used. A parallel empty space used to exist to the right of the roadway in each direction, through which the bridge's girders could be seen.
The space on the east side was converted into an additional traffic lane in 1956, and on the west side in 1959, bringing the total capacity of the bridge to five lanes. The roadway was expanded by an additional traffic lane on the east side in 1956 and the west side in 1959 to include the space allocated to the tramway tracks, adding an extra lane of traffic in each direction. The two sidewalks were outside the bridge proper.
To accommodate large ships using the new St. Lawrence Seaway, the span over the east channel of the river (the Warren truss) was raised an additional 80 feet (24.4 m) (to 120 feet or 36.6 metres) in 1957 and 1958. Traffic flow over the bridge was uninterrupted by this construction, through the installation of two Bailey bridges.
Originally, the bridge was constructed with only one ramp to Saint Helen's Island, located on the western side of the bridge. In 1961, a second ramp was built on the east side to prevent cars traveling to Montreal from having to cross the path of those heading toward Longueuil, a major source of accidents.
During 2001 and 2002 the entire deck of the bridge was replaced. The sidewalks were also widened to a width of 8-foot (2.44 m), and the sidewalk on the western side of the bridge was made a bike path.
In 2004, a suicide prevention barrier was installed. Until then the bridge saw an average of 10 suicides a year.
The bridge follows the general design concept of the Quebec Bridge. It was, in turn, one of the design influences for the Story Bridge, in Brisbane, Australia, which was completed in 1940. Interestingly, its imposing steel structure of its main section most likely inspired the designers of J. C. Van Horne Bridge spanning the Restigouche River between Campbellton, New Brunswick and Pointe-à-la-Croix, Quebec. This bridge was not built until 1958.[original research?]
The structure was a toll bridge from its opening until 1962 and a toll plaza was located on the southern approach. The toll plaza area now houses the offices of the corporation that owns and operates the structure and the nearby Champlain Bridge. Tokens were issued for part of the period that tolls were collected.

This bridge has been shut down several times due to several protesters who have individually climbed on the superstructure of the bridge or on a sign in the Longueuil side of the bridge. Two of them were from the Fathers for Justice group, while a third claimed he was part of the group. Recently, a man wearing a Canadian flag climbed the structure of the bridge. Most of the protests led to massive traffic congestion during rush hour. Recently, the pedestrian paths were modified with the installation of round metal fences all around in both directions, to disallow climbing of the superstructure and discourage potential suicide jumpers, the two main problems associated with pedestrian traffic on the bridge.
"Living Connections", the lighting of the Jacques Cartier Bridge
To mark both the 150th anniversary of Canada and the 375th anniversary of Montreal, the bridge was refitted in 2017 with new decorative lights. The project, "Living Connections" was designed and installed over a period of 3 years by Montreal based Moment Factory in collaboration with other local partners (Réalisations Inc. Montreal, Ambiances Design Productions, ATOMIC3, Éclairage Public/ Ombrages, Lucion Média and UDO Design).   The system, which allows for varying colors and animation, is scheduled to remain active until 2027. The interior lighting network changes with the passing of seasons, while the exterior lighting network uses big data, translated in real time to feed LED lighting networks on the outsides of the bridge superstructure. Réalisations Inc. Montreal is responsible for the idea of using big data as a modulator of the bridge lighting program, as well as the design and production of the custom software and training of on-site operators to bring this concept to life.
Fifty-three types of data pertaining to Montreal, across eleven categories, are tracked to feed the bridge's lighting systems, included but not limited to; weather, traffic, noise and activity on social media. The systems track this data using physical capture systems such as sensors and cameras as well as through hashtags and keywords on online platforms. More information on how data is interpreted and expressed in light, and the systems used to do so, can be found on the Réalisations website.
