Description
The project involved the construction of two tunnels between the future mixed-use large development Hullmark Centre and the existing TTC Sheppard-Yonge Station. Two ventilation shafts were also constructed for the TTC Station.

Intricate structural tie-ins were required under Yonge Street to the existing and operational TTC station.for the exhaust shafts while existing exits were tied into for the pedestrian walkways.

The work also included the fit out of the new ticket booth.
