Posted on July 4, 2012
The completion of the first 1.6 kilometres of twin tunnels for the Toronto-York Spadina Subway Extension was announced last week. The new tunnels represent one complete section of the twin tunnels that will connect the future Sheppard West and Finch West Stations. The tunnel boring machines (TBMs) named “Holey” and “Moley” bored the tunnels.
