Oh I don't disagree with any of that, I'm just saying that they're not overly big problems. Whether it's 50 feet or 90 feet, deep stations aren't uncommon and function perfectly well. Sure it would be expensive to build, but the DRL will get so much ridership that the expense will be well worth it. Subways by their very nature work best when they're built through densely populated, challenging environments. We've done suburban subways at the expense of downtown for so long in Toronto that it's easy to forget that.
TBH I’ve always felt the DRL will be a deep line regardless of the Don’s existence. Even without the river we’ve still got hurdles like the PATH, bored University/Spadina line, Enwave, enormous foundations for buildings in the financial district... There’s no question the DRL will be deep. It has to be.
I guess one reason I tried to poke holes in the idea of tunnelling under the Don is to garner interest in my “Don Line” fantasy map, particularly in how I used Riverdale Park as a location to bridge the DRL. Perhaps I wanted to make a point that it is still feasible and quasi-realistic to provide a non-tunnelled rapid transit alternative to cross the valley south of Bloor.
I also find Toronto’s physical geography and subsurface geology somewhat interesting, and worthy of sharing. The knowledge about what’s down below is still ongoing. After my post last night I stumbled on an EA concerning the future tunnelling of a Coxwell Trunk Sewer bypass through the Don Valley. In the report the engineering firm made some interesting acknowledgements about unstudied discrepancies in the Lower Don (e.g geophysical anomalies regarding bedrock valleys which warranted further borehole drilling). I made some relevant highlights that I may post some other time.
Wouldn't this be most desired? Tunnel under Adelaide, entrances to both King and Queen via escalators and PATH connections, convert Queen street to a pedestrianized street with streetcar ROW and remove King streetcar allowing for downtown traffic?
That's what I feel as well. Richmond or Adelaide make a great compromise in the long-running King vs Queen debate. And because of the depth, entrances and exits for the stations could be designed to lead to both King and Queen. And I feel either road would be easier to tunnel under and stage construction than King or Queen. And yeah, removing streetcars from one downtown street makes a lot of sense if there's a tunnel in place.
