The case study details the Samuel De Champlain Bridge Corridor Project which received the Envision Platinum Award for its Sustainability Performance.
The Samuel De Champlain Bridge Corridor Project is one of the largest transportation infrastructure projects in North America, and it is vital to the economic growth of Quebec and Canada. It is one of the busiest crossings in Canada, with more than 50 million vehicle trips per year. Due to its unique location, Montreal’s economy is directly tied to the Samuel De Champlain Bridge, allowing for Canada-US trade worth about Can$20 billion a year. After more than 50 years of operation, the old Champlain Bridge presented serious corrosion damage, mainly caused by the use of de-icing salts over the years and the lack of an adequate drainage system in the original design. In addition, the volume of traffic was much higher than designed for, contributing to accelerated degradation. Maintenance work became increasingly expensive and insufficient over the years. In light of these challenges, the new Samuel De Champlain Bridge Corridor Project was announced in 2011, aimed at improving long-term safety while meeting the evolving traffic demands in the region. Construction began in 2015.
The Project requested an evaluation of its sustainability efforts by Envision. The New Samuel De Champlain Bridge Corridor earned 67% of the total available points. The Project far exceeds the 50% performance required for the highest award. Receiving the Envision® Platinum Award in 2018, the Project became the first Envision®- recognized Project in the province of Quebec, the fourth in Canada overall, and the second bridge project to earn an Envision® award in North America
