Plaque Location: The plaque is mounted on a short pedestal at the west corner of St. Catherine E and Lorimier Streets (GPS 45.524750, -73.550627). Following the directions above, do not turn on Hwy. 134 but stay on Avenue Papineau for another 0.2 km. Turn left (north-east) on St. Catherine E, and continue 150 m. to the Lorimier Street intersection \u2013 the pedestal with the plaque on the left. It is one block northeast of the Papineau Station on the Metro Green Line. Bus Routes 34, 150 170, 358, 445 have stops nearby.<\/p>\r\n\r\n\r\n\r\n

Description: The Jacques Cartier Bridge, a five-lane bridge with a total length of 3.4 km (11240 ft.) that opened in 1930, spans the St. Lawrence River between the cities of Montreal and Longueuil. Its signature feature is a cantilever bridge with a main span of 334.4 m (1097 ft) and anchor spans of 128 m (420 ft.) each. It was designed by Philip L. Pratley of the consulting firm Monsarrat and Pratley. Contracts were awarded in 1925 to: Quinlan, Robertson and Janin Ltd. for the south shore piers ($936,000); Dufresne Construction Co. Ltd. for the north shore piers and approaches ($125,000); and, Dominion Bridge Co. Ltd. for supply and erection of the steel superstructure ($6,954,000). Subsequent work included: adding a fourth (1956) and fifth (1959) traffic lanes; lifting the bridge 24.4 m (80 ft.) to achieve clearance for the St. Lawrence Seaway (1958-59); and, full redecking (2001-02).<\/p>\r\n\r\n\r\n\r\n

Historic Significance: The bridge was originally named the Montreal Harbour Bridge and was renamed in 1934 to mark the 400th anniversary of Jacques Cartier\u2019s first voyage to Canada. It was the fifth longest cantilever bridge in the world when it opened. P. L. Pratley and the Dominion Bridge Co. Ltd. have iconic status in the history of Canadian steel bridge design and construction. Together they facilitated raising the Seaway span, and its approaches, using 30 massive hydraulic jacks with capacities between 320 and 500 tonnes (350 and 550 tons) while maintaining vehicular traffic.<\/p>\r\n\r\n\r\n\r\n
