Located next to the Beauharnois generating station, the Melocheville Tunnel is an extension of the regional route from Montreal’s south-west shore.
This tunnel is located directly under the Beauharnois Canal and allows for the ongoing passage of both road and maritime traffic. It links Beauharnois Downtown sector to Beauharnois West sector.
Total length of the bridge: 227.6 metres
Annual traffic flow: estimated at 1,7 million passings
In 1968, the tunnel was restored and resurfaced. Since then, maintenance work on the tunnel, such as pavement repairs, cleaning and painting of the walls, and restoration of the approaches, has been ongoing to preserve the structure’s integrity and to ensure users can use the tunnel safely and efficiently.
