Infrastructure Ontario (IO) and Metrolinx have announced substantial completion of the first set of tunnels for Toronto’s Eglinton Crosstown West Extension project.

The first Advance Tunnel contract includes two 6.3-kilometre tunnels stretching from west of Scarlett Road to Renforth Drive.

The contracting team, West End Connectors, completed the tunnels, cross passages, headwalls for future stations, utilities, and emergency exit buildings among other construction elements on June 30. The design-build-finance project was delivered through IO’s P3 model.

West End Connectors includes a construction team of Aecon Infrastructure Management Inc., Dragados Canada Inc., Ghella Canada Ltd. and design team of TYPSA Inc. and EXP Services Inc.

An elevated guideway and second set of tunnels are currently under construction under the second Advance Tunnel contract. The stations, rail and systems contract is in procurement.

Once work on all the contracts has been completed, the Eglinton Crosstown West Extension will bring Line 5 Eglinton another 9.2-kilometres west from Mount Dennis LRT station in Toronto to Renforth Drive in Mississauga.
