TTC Spadina Extension

TTC Spadina Extension

The Toronto-York Spadina Subway Extension Project (TYSSE) will provide a critical extension for the existing Toronto Transit Commission (TTC) subway system across the municipal boundary between the City of Toronto and The Regional Municipality of York. The south portion of the project extends from the existing Downsview station to the new station at Keele and Finch. VCL did long-term unattended noise and vibration monitoring of the construction.
