Le Gardeur Bridge, Beam bridge in Pointe-aux-Trembles, Montreal, Canada

Le Gardeur Bridge is a beam bridge of two separate structures crossing the Rivière des Prairies between Pointe-aux-Trembles, on the island of Montreal, and Repentigny. The two spans are joined by a curved 650-metre roadway across Île Bourdon. It carries four traffic lanes, two in each direction, with sidewalks and a bicycle path on the south side.

Built in 1939, the bridge was rebuilt in 2001–2002 by the engineering firm Dessau, with contractor Pomerleau, at a cost of about $26 million. The work widened the deck, added a reserved bus lane on the eastern structure, and rehabilitated 24 pillars. In 2020 it was renamed Pont Jean-Baptiste-Legardeur for Repentigny's 350th anniversary.

The bridge links two districts and serves as a daily crossing for residents moving between communities on both sides of the river. Pedestrians and cyclists travel on separate paths while taking in views of the waterway that divides the landscape.

The bridge is best explored on foot or bicycle during early morning or late evening hours when traffic is lighter. The well-separated pathways for both forms of movement make crossing safe and straightforward.

The bridge's two spans are unequal: the west structure from Montreal to Île Bourdon measures 590.6 m, while the east span to Repentigny is 332.8 m, joined by a curved 650 m causeway across the island. The east span carries a bus lane reserved for the Metrobus. In 2020 the bridge was renamed Pont Jean-Baptiste-Legardeur for Repentigny's 350th anniversary.
