Danforth Line 2 Scarborough Subway Extension

I can't speak for Broadway as well, but in Ottawa the station disruptions blocked all the key intersections, making the area inaccessible by cars and undesirable by pedestrians for longer than the cut and cover option would have taken, even though the points between stations were relatively unscathed.
In Ottawa, what do you mean by "inaccessible to cars"?

There's lane-width reductions and lane closures on West Broadway, but I'm yet to go down it and had any full closures. I'm sure that does happen on occasion - perhaps overnight?

Even on Eglinton, I don't recall any extended east-west closures on Eglinton - but to be honest I mostly avoided it, and personal circumstances are that I've seen a lot more of the West Broadway work than the Eglinton work.

I can’t wait for the Eglinton West extension station excavations to hit their stride….once those privileged central Etobicoke residents weigh in on disruption at the deep station sites, we may see legislation banning tbm’s altogether.
Which station would this be a problem for? There's huge swaths of land available there to dig holes outside the roadway, and to divert lanes while they are digging.

Back to this line, I haven't seen any closures, despite all the construction sites along Danforth and McCowan.

While overhead may be easier for avoiding construction woes in the community, when operational,they do pose a bigger problem in winter.

Queen street is a much narrower street than Eglinton or Broadway. The station shafts for entrances and ventilation required full intersection closures at Queen and O'Conner and at Queen and Lyon, and after partial reopening allowed only a single lane, so forcing unidirectional travel.

There was so little clearance between the tunnel and building foundations they actually bumped into one


Anyway this was a case where cut and cover wouldn't have been less disruptive. For Broadway they probably would have picked a TBM anyway, as they had to go deep to go under the Canada line. The point was that it was ruled out by politicians, not engineers. Politicians shouldn't be the one choosing the tunnel tech

Interesting. Looking at mapping, it looks like Queen is only 60 feet wide; 66 feet (one chain) is the norm in Toronto. While West Broadway appears to be 85 feet wide.

Cambie is 95-feet wide, so there's plenty of place to work around Broadway–City Hall station. That certainly appears to be the most intensive construction site - the other locations don't even seem to be particularly deep - but that's just judging by standing on the sidewalk, or peering down from the 99-B.

At least on Eglinton, the ROW is very wide, allowing for traffic to continue.

There were some hideous traffic problems especially from Mount Pleasant over to Don Mills.... turn restrictions, major closures, etc. It very much affected the ability to get from A to B.

More to the point - the need to place equipment and material along the sidewalks in proximity to the excavated locations choked the streets and suffocated sidewalk traffic to the detriment of businesses. And since much of this was left in place from the moment excavation started until the stations were fully erected and largely complete inside, the impacts existed for 5+ years.

Cut and Cover is a year of hell, but not five years of it.

While Martin Grove, Kipling, Islington, and Royal York all locate the stations north of the current roadway, all of these sites are pretty space constrained, some by buildings and others by woodlot. So I expect there will be a lot of lane narrowing, pylons and jersey barriers, let alone vehicular traffic (dump trucks and then cement trucks). Lay-down areas will be not as easy to manage as one might imagine. North-South routes may not fare as badly, but Eglinton itself will be even more of a parking lot.

Finch and Keele would be comparable. It was a disaster zone for one to two years, has only just got back to normal.

That level of disruption will not play in central Etobicoke. Frail, frail constitutions out that way. (Trust me, I live there)

Ironically that's the piece I may have used a bit during construction!

The big construction for the stations will take more than a year; they can't even put in an elevator that fast. And I doubt they could build 10 km of cut-and-cover tunnel in the year. The hydro work alone would probably take more than that. Not to mention the new sewers.

After what they did to Moss Park, and Osgoode, I think a wood lot would be history, if it's in the road allowance.
 
Not sure if this is the right thread, but here's photos from a SRT corridor repurposing design charette event I attended last Tuesday with Jamaal Myers doing part of the opening speech.

A little bit of background info on Line 2's extension itself, some questions asked about tunnelling and the response to that was "we're progressing with tunnelling as the sites have been cleared"...

Also a bit more on the future secondary plan and how the subway station will somehow be the centre of all the development? It was also mentioned there wouldn't be an underground connection to the STC mall but a space has been future-proofed.

Did they mention any updates on how the station is coming along?

The site just east of mccowan near the old mccowan station is a barren land now that all the rubble has been removed.
 
Why is TTC/City holding onto McCowan Station and the guideway? Looks like it’s impeding full development of this site and GreenP.
Are they going to build SRT phase2 to malvern after all??? LOL just my humor I’m not serious.

All joking aside I was wondering the same thing. You think they would have tore it down when they ripped down the Progress Avenue Bridge.

It's not like that bridge serves any useful purpose anymore.
 
In a similar vein, is there any possible future use of the upper level at Kennedy? I'm wondering if eventually they'd just demolish the whole thing and build a new bus terminal

Only 2 uses I can think of: Eglinton LRT East platform or convert the top level into management offices / break rooms for operators, janitors etc etc.

Why, though? What's wrong with the old bus terminal? I mean, apart from the Dubious Fluids that drip down on you from Pipelines Unknown, which is a problem that could be solved with a renovation, an approach which is cheaper, much less disruptive, and more environmentally friendly. There wasn't a problem with it until they started the construction works for the Crosstown, and it will be fine again when the SSE ends.

The upper level I suspect will suffer a similar fate as the old terminal at Wilson - it will be used as a storage space for Crap And Stuff. It could've also been a great place to store the SRT cars they or may not actually be saving, but I think that ship has sailed.
