A consortium made up of engineering firms exp, Stantec and CIMA+ has been awarded a contract by the Ministère des Transports, Mobilité durable et Électrification des transports (MTMDET – ministry of transportation, sustainable mobility and transport electrification) to prepare preliminary and definitive pre-project studies, plans and specifications, as well as preliminary and definitive schedules, for the Île-aux-Tourtes Bridge, located on the western tip of the Island of Montreal and spanning the Lake of Two Mountains between Senneville, and Vaudreuil-Dorion.
The project mandate includes providing the engineering services needed to support the MTMDET in monitoring and maintaining the existing structures of the Île-aux-Tourtes Bridge in order to ensure the safety of users.
The primary objective is to plan work on the existing structures over a five-year period in order to maintain traffic safely until the 50-year-old bridge, opened in 1966, is fully replaced over a projected 10-year horizon.
The engineering structure teams of the consortium’s three firms have carried out numerous inspections, studies and operations on this bridge in recent years.
In a news release, Vincent Latendresse, vice-president, engineering structures at exp in Quebec and team leader for this mandate, says: “This project involves major technical challenges and issues that are rarely encountered, as a result of the original design. Through our involvement in the inspections and pre-project studies focused on the Île-aux-Tourtes Bridge, we have gained in-depth knowledge of the structure, and that expertise will enable us to monitor the situation effectively and ensure that the structure will remain safe for many years to come.”
