Thanks for the pictures. With all the talk about Scarborough, Smart Track and cost overruns on Spadina I think many people forget a major line is currently under construction across the middle of Toronto.
 
It may be a silly question, but why didn't they tunnel under the Spadina Subway? Don't they have to eventually do that anyways?
 
Ok, so the problem will still have to be addressed on the future.

I'm not sure if it's a problem. I'm not an engineer, but it doesn't seem too big of an issue to shore up the tunnel with steel beams and excavate while the subway is running.

It would have to be addressed in the future anyways. If you'd have kept tunnelling under the existing station, you'd still have had to have dug down to build the platforms and remove all the tunnel segments. And you'd have had to have been deeper under the existing track than if you did it the way they are planning.
