More than 300,000 vehicles use the Turcot interchange every day, 10% of which are heavy vehicles. The owner, the department of Transport, Sustainable mobility and Electrification (ministère des Transports, de la Mobilité durable et de l’Électrification des transports - MTMDET), had to schedule a full rebuild in order to reduce the very high maintenance costs.
The MTMDET has been preparing for this major project for several years, investing in the planning and execution of several pre-project studies and processes, as well as in the construction of preparatory structures using traditional methods. In February 2015, the MTMDET awarded KPH Turcot the final design and construction mandate for the main Turcot Project infrastructure (2015-2020). The KPH Turcot consortium is a partnership of Construction Kiewit Co and Parsons Canada Ltd, with Holcim Inc. and WSP as participants. Simultaneously, WSP was awarded the contract for stormwater management for the Turcot interchange project. Consequently, in addition to the rebuilding of the interchange, construction of numerous water management structures was planned, including surface retention ponds, line retention, flow controllers and two pump stations.
Large Scale and Complex Project
The objective of this design-build project is to build a complex of interchanges and highways connected to the existing road network, capable of providing users with a high level of road safety, service and comfort while maximizing the infrastructure’s lifespan.
The project includes:
- Rebuilding four major interchanges and sections of three highways;
- Moving a section of highway and railway to allow for future development of the Turcot Yard;
- Adding dedicated lanes for modal transport (bus and taxi);
- Significantly reducing the number of structures;
- Improving the geometry of the road layout;
- Re-establishing conventional east-west traffic flow on the A-20;
- Building new links to the local road network;
- Adding bike paths.
