Introduction


The Honoré Mercier Bridge spans the St. Lawrence River and Seaway between LaSalle on the Island of Montreal and the Mohawk Territory of Kahnawake on the South Shore.

Named for former Quebec premier the Honourable Honoré Mercier, the bridge became the third structure to link the Island of Montreal and the South Shore after the Victoria Bridge (in 1860), the Lachine bridge (in 1885) and the Jacques Cartier Bridge (in 1930).

The opening of the Honoré Mercier Bridge in 1934 provided a new route into southern Quebec from the Island of Montreal. It also reduced the distance between Montreal and New York State by many kilometres.

Today, an estimated 30 million vehicles cross the Honoré Mercier Bridge every year.
