Transport Canada has selected a consortium that includes Arup to advise on the initial phases of replacing Montreal’s deteriorating Champlain road bridge.
The current structure, which spans 3.5km over the St. Lawrence River, is understood to be Canada’s busiest crossing point.
The project is expected to be delivered as a public private partnership (PPP). The consortium’s remit is to prepare a business case for the new bridge, which will be located slightly downstream of the existing structure.
The consortium also includes PricewaterhouseCoopers, Morrison Hershfield, Groupe SM and SDG and together the firms will prepare a recommended design for procurement and construction.
The team is now reviewing previous work done on the project and developing 8 new design options for initial review. The project’s technical challenges include the need to create an aesthetically pleasing long-span crossing with a 125-year design life that can withstand harsh winter conditions and river ice flows.
