TORONTO — Construction is complete on the tunnelling component for the Eglinton Crosstown West Extension, which will extend Line 5 Eglinton by 9.2 kilometres.
According to a release, crews have completed excavating twin 500-metre tunnels from Mount Dennis Station to Jane Street for the eastern underground segment of the Eglinton Crosstown West Extension.
Tunnelling for the western underground segment, running 6.3 kilometres from Scarlett Road to Renforth Drive, was completed in June 2024.
The twin 500-metre tunnels that form the eastern underground portion of the Eglinton Crosstown West Extension were built via sequential excavation, with crews advancing one to two metres under Eglinton Avenue West each day.
At Jane Street, trains on the Eglinton Crosstown West Extension will run above ground on an elevated guideway to Scarlett Road before transitioning to the western underground portion of the line.
Once complete, the Eglinton Crosstown West Extension will extend Line 5 Eglinton farther west, creating nearly 30 kilometres of rapid transit along Eglinton Avenue, linking Scarborough, Midtown Toronto and Mississauga into a single continuous transit line.
The extension will add seven stations to Line 5 Eglinton, offering connections to UP Express, GO Transit, TTC and MiWay.
The Government of Canada is supporting the construction through an investment of approximately $1.87 billion.
