Autoroute 30

Montreal, Quebec

The 42-kilometre western extension of A-30 was delivered as a Public-Private Partnership (P3). A consortium comprised of Aecon, Acciona Infrastructures Canada Inc., Dragados Canada Inc. (an ACS subsidiary), and Verreault Inc. was responsible for the design and construction mandate of the project.

Montreal’s Autoroute 30 (A-30) project was one of the most important transport infrastructure projects undertaken in Quebec in the past 50 years. The completion of the new A-30 toll road greatly alleviates congestion in the Greater Montreal Area, with a consequent reduction in air pollution. The highway links the A-20 and A-540 routes from Toronto and Ottawa, where they converge at Vaudreuil-Dorion, Quebec. The new A-30 routes traffic along the south shore of the St. Lawrence River, tying into the existing A-30 at Chateauguay leading to Quebec City.

Aecon executed the project through sustainable engineering and construction practices that considered all economic, environmental and social aspects of the development. Highway design considerations included working in soft clay, short construction periods, and cold weather conditions that significantly influence options for embankments, abutments, and foundations. Bridge design considerations included ship impact assessments, seismicity, wind, river hydraulics, and ice.

During construction, special attention was focused on waste reduction by reusing much of the existing material from excavation and using recycled materials in fills, aggregates and concrete. This project was constructed with the highest regard to the environmental impact study, done in accordance with provincial regulations. The specific guidelines outlined in the environmental impact study required the project to be engineered and constructed following measures to minimize noise, dust and water contamination. Complying with these measures was essential to protect wildlife habitats, and AECON worked very closely with environmental and ecological consultants to ensure that impacts are minimized.

Scope of work included the construction of a 42-kilometer, dual two-lane highway, two large bridges crossing the St. Lawrence River (1,800 m long) and the St Lawrence Seaway/Beauharnois Canal (2,500 m long). Other project features include 30 other bridge structures over rivers, existing roads and railways, as well as a short tunnel under a canal.

The project was delivered on-time and on-budget and the consortium was recognized with a Gold Award for Innovation and Excellence by the Canadian Council for Public-Private Partnerships (CCPPP). Project Finance International, a specialist publication, also named the project the North American Deal of the Year.
