No, The Sheppard subway passes overtop of the East branch of the Don. When you take the cycle path to the south-east of Leslie and Sheppard, you are riding on the bridge.

Ahhhhh thank you!

Yes, the TTC always seems to find new ways to make building subways as prohibitively expensive as possible. New builds being exclusively underground 100% of the route like what was done for TYSSE sets a bad precedent.

To be fair there are few areas where it could be built above ground, and the cost savings of elevated vs tunneled aren't all that much. And you have the advantage of tunneling being far less disruptive when being built.

Subways are expensive. The Canada line in Vancouver is a good example of doing things inexpensively, but it is severely under-built and there was questionable labour practices.

The consortium who built the Canada Line got sued and lost for blocking businesses and making them suffer by a complete cut and cover approach to build the line. Inexpensive, yes. Completely pissed off everyone who lives and does business there. Absolutely too. It's not 1949. The public also gets angry if they build it like the Yonge or Bloor-Danforth Subway.

Tunnel versus elevated is similar but an underground station, particularly 30m deep, is 10x the cost of an above ground station; same is true of emergency exits.

Some of the techniques used in Barcelona on L9/10 (still under construction) are interesting. It'll be interesting to see how well the limited elevator/stairwell capacity handles an emergency evacuation; if they hold up then it'll greatly reduce station construction.

Rosedale subway bridge used to have open slots overhead, but NIMBYs complained, so it was sealed up.

TTC and City were probably being quick and cheap when they did this. No question we could've used plexiglass, thus allowing daylight and quiet. Don't do the Twitter, but if anyone can message whomever is now in charge of TTC and tell them to consider replacing the metal covers with glass, it'd be much appreciated.

That is absolutely not the reason why they sealed those holes.

When the upgraded ventilation system was being planned at Castle Frank station, the holes in the roof were found to diminish its effects. They were only sealed up at that point.

It's one of those archetypal Toronto things. Any mention of cut and cover gets instantly shouted down by people with photos of Yonge street in 1951. But no one remembers the last project we tunneled.

Those are the boomers who complained about that

I live on Eglinton near Bathurst and they could have done the same thing at Allen but people who were consulted wanted to keep the allen open. Sometimes consultations suck. people sometimes think they know what they want but in the end prefer it the other way. Eglinton has been a disaster and I would much rather this thing been done sooner than later. No more delays.

This exactly.

This is a hot take, but I am beginning to think that Toronto/Ontario has been a very good social experiment in regards to the value of public consultation in major infrastructure projects. But the results is not as impressive, positive, effective, or efficient as imagined, and participation remains abysmally low despite millions of dollars in sunk cost.

Now that the last ION Flexity Freedom has been delivered to Waterloo, the attention now turns to Crosstown manufacturing and deliver;y.

Well, are the tracks ready ?

20% complete, according to metrolinx

Still a long ways to go before the LRVs can start testing then, to answer others questions

About 1.5 to 2 years until LRV testing starts, according to their tweet yesterday.
