LEA Shortlisted: Eglinton Crosstown West Extension Advanced Tunnel Project

Infrastructure Ontario (IO) and Metrolinx have shortlisted three teams for advance tunnelling work on the Eglinton Crosstown West Extension project.

LEA is part of the North American Tunnel Partners design team taking on Civil and Structural Design roles. The shortlisted teams will prepare detailed submissions over the next year. IO and Metrolinx expect to award these tunnelling contracts in mid-2021.


The Advance Tunnel Project will include approximately 6 km of tunnelling for the 9.2 km Eglinton Crosstown West Extension. The project scope includes design and construction of launch and extraction shafts, tunnels, as well as headwalls for emergency exit buildings and stations; supply tunnel boring machines (TBMs) and install segmental precast concrete tunnel liners; and activities necessary to build the tunnel including, utility relocations, supports for shaft and headwalls, temporary power supply, lighting, ventilation, and drainage.

Once completed, the Eglinton Crosstown West Extension will improve access and travel times for commuters in the area, encourage economic and community growth along the transit line, and reduce congestion to improve our roadways and our natural environment.
