Danforth Line 2 Scarborough Subway Extension

Interesting. I guess it's semi-official now that it will be a single bore design with side platforms. There is benefit to this vs dual tunnels, and I wouldn't be surprised if this ends up how the RL is designed as well.
 
Just to clarify - in case I missed something - this plan removes the need to rebuild Kennedy station?

And I don't see a direct explanation for why tunnel boring(and a big tunnel at that) is the preferred option. Assuming this is the chosen routing, what would the cost savings be if the extension were built cut and cover instead?

They clearly dismissed cut and cover from being studied for the McCowan corridor. So no need to rebuild Kennedy. Also, the savings of using the SRT corridor is too small, which would shut down the SRT for like 6 years on top of complicate the TTC operations by having to run a shuttle bus service (more buses and drivers would be needed). Finally, it would not support the new vision for Scarborough Centre.
 
The triton terminal is also clearly the superior option. More land could be used if the mall was to sell some of it. Anyways, it's great to see what STC might become and it's a most welcome change to the area, which greatly needed it

According to this, using the SRT corridor barely saved any money (up to $500M) and added the inconvenience of shutting down the SRT and most likely incurring increased costs to the TTC and a 6 years nightmare transit scenario in Scarborough.

So we have our answer on why the SRT corridor is a no go.

Even going with this number, 1/6th to 1/7th of the project budget is hardly "barely any" money.

I hope that the Lawrence/McCowan station gets readded to the plan.

Also I hope that some sort of BRT (possibly the Highway 2 BRT in Durham Region) serves Centennial College so that we can reduce the main disadvantage of the subway vs the LRT.

Especially since this amount could be spent to push the Crosstown extension a little bit further north - say to Malvern.

But yeah, the Brimley route may trigger a little more development. (We do have enough courage to stare down the NIMBYs who will want the subway but not the impact, correct?)

But other documents also shows that this alignment is the most optimal choice for potential growth and revitalization which they clearly took into consideration. The SRT wouldn't be able to deliver what the McCowan corridor does. Just looking at what the Triton Terminal does and all the extra land that can be redevelop, its clear the SRT was an obstacle to STC full potential.

However, I'm disappointed that cut and cover wasn't even considered which would have brought the cost down
 
Looks like the Chief Planner's bluff has been called. The LRT is fast approaching "Sheppard East" status, and she is not namechecked on the Staff Report as author or as consulted (as Byford was).
 
What do you mean?
  • The 1 stop subway plus Crosstown East was sold as Keesmaat's compromise within a single $3.56bn envelope, which SSE has now swallowed all but $200m of (less, if you go with peer review figures).
  • In the Staff report, the authorship is "City Manager, Deputy City Manager & Chief Financial Officer, and Deputy City Manager Cluster B" with para 1 reading: "This report was prepared in collaboration with the Chief Executive Officer of the Toronto Transit Commission (TTC)."
 
New ridership and job numbers are worse than in earlier business case.
  • 10,900 jobs within walking distance of proposed station, down from 12,100 in June report
  • Projected job growth within walking distance is now 2,400, down from 2,500
  • Projected future jobs in area now 13,300 instead of 14,500
  • Projected net new riders have dropped from 4,500 to 2,300


The math on that is the city would be spending $1.45M per new daily rider to build this subway extension. Also remember that as of last summer, projected peak hour ridership had been revised down from 14,000 to 7,300. That magical 14,000 persons/hr figure is what convinced council to kill the LRT (so much for that argument).

So all the while, estimated cost has been increasing, while infrastructure to be delivered within the funding envelope has been decreasing. Today's report doesn't update the cost estimate, it just adds a bus station. $3.346B is a 5% estimate. It will grow. This is a slow-motion bait and switch leading to an outcome that would never have been reasonably contemplated at the outset, to say the least. Not that John Tory will ever admit that. "Logic says an express Scarborough subway makes sense", he said today. Okay then.
