Design and Construction of the New Champlain Bridge, Montreal, Canada.

The New Champlain Bridge is a highprofile infrastructure project in North America due to its critical economic importance, the premature deterioration of the existing structure and its visibility throughout the metropolitan area. As the gateway into Montreal, significant architectural input is encapsulated in the project design criteria. Durability is a key aspect of the design with a 125 year service life specified. One of the most significant factors in the design, however, is the compressed construction schedule. The crossing is scheduled to open to traffic on 1 December 2018, with the notice to proceed announced in May 2015, permitting a total design and construction duration of just 42 months. Key elements of the design and construction which allow the project to be completed within the short timeframe, while meeting the challenges of environmental constraints, durability requirements and architectural considerations, are explored in this paper.
