i agree we should use the existing bridge and then continue to tunnel afterwards.

You know, that's not such a crazy suggestion at that point -- you've tunnelled through Leaside, pop out across ET Seton to use the bridge, then tunnel rather than make the train climb the grade up to Don Mills. It would allow you to have an underground station at Don Mills & Eg (in a perfect world, you'd connect an underground walkway into the Science Centre by using its surface parking lot for the station and add parking under/over the station, for commuters and OSC tourists. (In an even more perfect world, you'd run an LRT down Don Mills to connect into my new commuter transport hub.))

However, and with this mayor it's a huge but... you pretty much need to come back above ground on the other side of Don Mills until you get up the hill past Bermondsey. That'll be a game breaker for His Worship, 'cause an underground station with surface tracks will be diametrically opposite his vision.

cars could use wynford to avoid crossing the lrt tracks

 

[GraphicMatt]

Can they run in-median over the bridge and still use automatic train operation?

Because if not, it's really hard to come up with a business case for underground operation beyond appeasing the whims of a mayor who is, by all accounts, pretty damn unpopular.

At least let council debate and vote on it. We could presumably save a lot of money on Eglinton and use that money to provide some kind of enhanced transit service on Finch.

Can they expand the bridge and run the tracks to the south of the current traffic lanes?

You sure about that?
Knowing your Mayor, he'll probably salivate at those savings so that he could put it towards extending the Sheppard line.

You'd think so, but he's the one that's insisting on going underground for that whole stretch. He's a complicated man...

I don't see why not. There are quite a few heavy rail metros in the world that emerge from an underground tunnel to cross a major river on a bridge in the median of an arterial road. Here's an example of this in Rome.

All you would really need to do is erect a tall fence on either side of the ROW to prevent trespassing.

Exactly.
There aren't any intersections on the bridge, are there? So it's still exclusive right of way - just fence it off.
I really don't see what the fuss is all about.

Isn't the big issue here, the Don River crossing between the Don Valley Parkway and Bermondsey, not the smaller west branch crossing between Leslie and Don Mills road, which seems to not be such a big deal, and would only require a bit of modification from the currently approved plans.

Though I'd think something akind to what they were already planning, with an extra portal somewhere west of Bermondsey is the simple answer.

Well if this crossing is to be underground, there are no approved plans.

As long as it doesn't stop at any red lights...I just don't trust the city and TTC over priority lights for Transit.

I can't for a minute imagine it would be underground. The Sheppard line crosses the same branch further north, and it's a bridge there.

The good news is this would be the only point where the LRT line would meet a set of red lights, and this also happens to be one of the stops. Its not a big deal if the LRT stops at Leslie, and also not a big deal if the LRT needs to hold the light green so it can go through. The trains will be travelling several minutes apart, and will take a few seconds to cross the intersection. Barely any inconvenience for transit riders or drivers.
