Following a year-long pursuit, WSP is proud to be a key member, in partnership with Hatch, of the Design-Build-Finance (DBF) team that was awarded one of Montreal’s highest profile projects: Rehabilitation to the Louis-Hippolyte-La Fontaine (LHLF) Tunnel. The team leading the DBF project is comprised of Eurovia, Pomerleau, and Dodin Quebec. WSP will co-lead the design team.
The 1.4 km long immersed tube tunnel opened to traffic in 1967 and is currently used by 120,000 cars per day to travel between Montreal’s east end and Charron Island. The main objectives of the project are to increase the lifespan of the tunnel by 40 years and to modernize it to meet current standards. The work will take place over four years, until 2024.
The project also includes the widening of 11 km of Highway 20, the addition of a dedicated public transport lane with preferential measures for buses on a stretch of 20 km on the same highway, and the addition of incentive parking spaces at four different parking lots. This work will be carried out with the aim of improving user mobility in the area. The work will also include the reconstruction of and upgrade of Highway 25, which includes the replacement of the paved road surface with a concrete slab surface.
One of the key project challenges is to carry out this reconstruction work while maintaining two lanes of traffic in each direction.
Critical to local supply chain
This link is an important vector for the economy of the Montreal region and for all of Quebec. This link connects the Port of Montreal to the highway network. It contributes to the mobility of goods all across Quebec and in eastern North America. The tunnel is a crucial transportation link supporting the local supply chain, and 13 per cent of its daily traffic is comprised of transport trucks.
“The tunnel is a mission-critical transportation hub that supports so many aspects of daily life in these communities,” said Éric Vaillancourt, Director Alternative Delivery of Transportation at WSP. “Our team of world-class experts is energized and honoured to have the opportunity to work on such an impactful project and critical link for the entire region.”
