Two consortia have qualified to submit proposals for the refurbishment of the tunnel between Montreal and the South Shore.

In 1949, the Canadian federal government decided to build the Trans-Canada Highway and, in 1960, the construction of the Quebec section was announced. To link the highway networks on either side of the Saint Lawrence river, the chosen solution combines a bridge with a tunnel that passes under the river bed, with the two meeting in the middle of the river on Charron Island.

Thus, the Louis-Hippolyte Lafontaine bridge-tunnel was inaugurated in 1967. It constitutes a major regional road link, both for Quebec and for Canada, for passenger transport and the movement of goods. It forms an integral part of the Autoroute 25 and comprises the longest underwater tunnel in Canada (at 1.5 km) and a bridge of 457 m in length.

The Quebec Ministry of Transport is currently planning a major project to refurbish the tunnel, so as to ensure its sustainability for the next 40 years.

A consortium made up of Eurovia, Mobility, Dodin Campenon-Bernard and Pomerleau is one of the two selected by the Ministry to submit a design and build proposal for this project.

Within the consortium, Mobility offers its particular expertise in the challenges of modernising electrical, lighting, ventilation and traffic management systems.
