THE NEW CHAMPLAIN BRIDGE - TECHNICAL REQUIREMENTS AND DELIVERY STATUS REPORT

摘要

In June 2015, the Government of Canada awarded a 3.98 billion dollar contract to the consortium Signature on the Saint Lawrence Group to design, build, operate, maintain and finance the undertaking of the new Champlain Bridge Corridor Project. Procured as a public-private partnership, this new project entails a new replacement crossing over the St. Lawrence River in Montreal and represents one of the largest bridge projects currently underway in North America. This new major transportation infrastructure, extending over a length of some 3.3 km will provide six vehicular traffic lanes, two lanes dedicated to a mass transit corridor and a multiple-use pathway. With reconstruction of its companion crossing over the western arm of the river along Nuns' Island, a combined deck surface of some 193,000 m~2 will be constructed, making the new Champlain Bridge Canada's largest bridge. This paper summarizes the technical requirements imposed by the Government of Canada to guide the bridge design and material selection. It also explains the approach used to develop the architectural features of the bridge and the technical requirements so as to ultimately endow Montreal with an elegant and highly durable structure (125-year design life). The paper also highlights some of the major construction techniques that have been selected and developed by the Private Partner to meet the demanding technical requirements and to ensure that the new bridge will be delivered on time. Finally, the paper summarizes the status of the bridge construction and presents a glimpse of the challenging and impressive works to come.
