Located only about 400 m south of the St-Laurent Railway Bridge, on the same line, is a pair of vertical-lift bridges to carry the rail line over the Saint Lawrence Seaway.

The Saint-Laurent Railway Bridge is a Canadian Pacific railway bridge linking LaSalle to the Kahnawake Mohawk Reserve, just upstream of the Mercier Bridge. It is used by the AMT Delson-Candiac commuter train. CSX trains, via the Montreal Subdivision, also use this bridge.

History of the bridge[edit]

1885 bridge.

There have been two bridge that cross the river at this location. The first bridge, erected in 1885-1887, was an all-steel construction that employed a flying cantilever design to cross the main channel. It was of a single track configuration.

The second structure (that still stands today), was rebuilt to a double track standard between 1910 and 1913. To build the bridge, the free ends of the main spans were floated across the water on a barge. [1]
