List of bridges to the Island of Montreal

This is a list of bridges in Montreal.

The construction of the Saint Lawrence Seaway in the 1950s required large changes for all bridges that existed at the time. Those are not reflected in the table below.

All three spans across the Ottawa River East Channel are twinned by another span, built simultaneously, across the West Channel.

^A The section of Honoré-Mercier bridge spanning over the St. Lawrence Seaway was rebuilt to seaway standards in the 1950s. The bridge was twinned by an identical one, on the downriver side, which opened in 1963.

^B The Champlain Bridge Ice Structure, known in French as "l'Estacade Champlain," was built to control ice floes coming from the Laprairie Basin.^[1]

^C At the north end of Champlain Bridge, two spans, one north-south (aut. 15 and 20) and one east-west (aut. 10) connect Île des Sœurs to I. of Montreal. These two spans, called Pont Île-des-Sœurs and Pont Clément, are part of the Champlain Bridge complex.

^D Victoria Bridge was built as a one-track tubular bridge which opened in 1860. It was the first bridge to cross the St. Lawrence River, and the longest bridge in the world. It was rebuilt as a two-track truss bridge in 1898. The South Y approach was rebuilt around the Saint Lambert locks of the St. Lawrence Seaway in 1961.

^E Pont de la Concorde (Concorde Bridge) and Pont des Îles ("Bridge of the Islands") were built for Expo 67.^[2] Pont de la Concorde connects Montreal Island to Saint Helen's Island, while Pont des Îles connects Saint Helen's Island to Notre-Dame Island.

^F Jacques-Cartier Bridge was originally named Harbour Bridge/Pont du Havre, and renamed after Jacques Cartier in 1934 (400th anniversary of Cartier's first voyage). The section over the St. Lawrence Seaway was lifted to a new height in 1962.

^G The Louis-Hippolyte Lafontaine complex consists of a tunnel from Montreal to Île Charron and a bridge from Île Charron to the South Shore.

^H Construction of the Highway 25 Bridge started in early 2008 and was finished in May 2011. It is a toll bridge.

^I The Rivière des Prairies hydro complex is a set of three dams: one from Montreal I. to Île de la Visitation (west of the Papineau-Leblanc Bridge), which includes a footpath; another between Île de la Visitation and Île du Cheval de Terre; and the longest span between Île du Cheval-de-Terre and Île Jésus. Île de la Visitation is joined to Montreal by another two small bridges: a road bridge, which also serves as a dam (historically, a water mill) and a footbridge.

^J The railway crossing at Île Bigras consists of two spans, one north and one south of Île Bigras.

^K A structure known as "Île Bray Bridge" was abandoned while still under construction in favor of Île aux Tourtes Bridge.^[20]

^L Galipeault Bridge was first built in 1925 and doubled in 1964. Both spans have been replaced since. Taschereau Bridge, which was part of the same project, spans the West Channel along the same highway.^[20]
