Lachine Canal National Historic Site


The Jacques Cartier and Champlain Bridges Incorporated

Detour set up for the section of the Lachine Canal bike path under the Bonaventure Expressway in Montreal

Longueuil, April 9, 2014 – The Jacques Cartier and Champlain Bridges Incorporated (JCCBI) would like to advise cyclists that a detour will be set up on the section of the Lachine Canal bike path that passes underneath the Bonaventure Expressway, from April 21 to May 15, as well as from November 15 to late December.

This detour is necessary to begin mobilizing major work planned for this year on the federal section of the Bonaventure Expressway at the Lachine Canal.

During these periods, cyclists will be invited to use a detour set up on the Wellington Street Bridge via the existing bike path network. See map of the detour (PDF, 1.5 Mb).

To minimize impacts on cyclists and pedestrians, a clearly defined path will be made through the construction site from May 15 to November 15, in order to keep this section of the Lachine Canal bike path open during the busiest time of the year.

Cyclists and pedestrians are asked to be careful around this major worksite.

As well, the detour will occasionally be re-implemented for 72-hour periods during complex manoeuvres between May 15 and November 15. During these periods, the path through the worksite will be temporarily closed.

To follow the progress of this work and the occasional closures, we invite users to visit our website at:

After five months of work, Parks Canada is pleased to announce the reopening of the Lafleur Bridge, which connects Dollard Avenue in Lasalle to Saint-Pierre Avenue in Lachine. This repair work is part of Parks Canada’s ongoing efforts to improve the condition of its infrastructure.

Work on the Lafleur Bridge included demolition and reconstruction of certain elements of the bridge deck, replacement of the road surface, partial demolition and reconstruction of the backwall, replacement of the curbs and demolition of the loose concrete on the counterweight surfaces. This work was in addition to the significant work carried out in 2006 on the structural elements of the Lafleur Bridge and its neighbour, the Gauron Bridge.

With the reopening of the Lafleur Bridge to traffic, Parks Canada would like to thank motorists for their patience and cooperation.

Quick Facts

  • Built in 1959 by the Dominion Bridge Company, the Lafleur Bridge is a Scherzer Rolling Lift Bridge. The Bridge is 38.2-metres long and 7.9-metres wide.
  • Located in Montreal, the Lachine Canal runs 14.5 kilometres from the Old Port to Lake Saint-Louis. The Canal is more than an inland waterway, as it is also an accessible urban park that astonishes with its rich history.
  • The Lachine Canal’s pathway system was ranked the third most beautiful urban circuit in the world by Time magazine in 2009.


“Since the Lachine Canal re-opened to recreational boating in 2002, Parks Canada has continued to help with the revitalization of the sector. We are proud of the results we have today when we look at the new Lafleur Bridge.” - Luc-André Mercier, Director, Quebec Waterways Unit, Parks Canada
