The Eglinton Crosstown LRT is a $5.3 billion light rail transit (LRT) project in Toronto.

The new 19 km LRT line will run across Eglinton Avenue between Mount Dennis (Weston Road) and Kennedy Station, and includes a 10 km underground portion between Keele Street and Laird Drive. The line will provide 15 underground stations, including two subway interchanges and two terminal stations, 10 at-grade stops, a vehicle maintenance and storage facility, an operations control centre, and other supporting infrastructure.

The project is procured as a Public-Private Partnership (P3). Entuitive is completing the structural design of three underground stations, including Allen Station, one of the major station interchanges with the TTC subway. The design scope includes below-grade stations, pedestrian and ventilation tunnels, and surface structures for entrances/access, substations, and ventilation equipment. Tunnel interfacing and excavation support for protection of existing structures and utilities are key design requirements. The interchange station scope also includes modifications to the existing TTC station for interconnection with the subway.

Entuitive helped pioneer the use of soil-structure interaction for the structural design of the below-grade stations based on our work on overseas projects. This development generated significant reductions in concrete thicknesses and reinforcement quantities, leading to the least cost solution for the below-grade stations on the project. Entuitive also developed structural solutions to account for the complex subsurface and groundwater conditions at the station sites. Structural designs were coordinated with the numerous subsurface utilities, which in some cases were governing considerations for the design of the structure.
