I always wondered that too. Was the Broadview extension not approved when construction started here? It's wild that they're going to have to tear up what was built only a couple years ago to make room for Broadview.

Good Lord. Metrolinx planning at its finest. They’re literally going to disrupt and dismantle what they just completed. I can’t.

Wow you can really see the western side of the bridge that’s being built for the Broadview extension in the 2nd photo but the east side seems of the GO tracks seems like there is no underpass beneath the eastern portion that was built in the last couple years by east harbour… Shouldn’t the eastern side of the GO tracks already been bult/framed as an overpass to allow Broadview to run freely underneath it? I’m so confused lol

The plan was always to come back and build the south/east potion of the overpass and station after the north/west part was completed.

Hell, one of the two tracks are not even in their final positions where they sit today - the northern track is on what will eventually be a platform and the vertical accesses to it.

I haven't been by the Queen, Dundas, or Logan bridges in awhile. Swung by today for a peek...

Is it just me or is the bridge reconstruction for Dundas and Logan currently going a lot faster than when they were building the GO bridge?

Well, when you consider that they were poking away at all of it from the beginning…

The plan all along was to built the northern side first, install new tracks on that side, tear us the existing tracks, and build the aouth side platform once the north side is open. I doubt that Broad ire changed that. The existing tracks have to be shifted to where the new platforms will be.

Because they would have had to build the south GO platform and the south half of the underpass first, before moving them then.

You've lost me but thanks for your input.
 
Near as I can tell, putting the original plan on top of @kotsy's latest aerial shot, one can see that a lot of the existing earthwork that the two active tracks are resting on will be moved around to support the south platform, and the tracks will generally shift northwards.
There will have to be another stairwell excavation and pour (bottom right)

Can you try phrasing your question a bit better, perhaps?

I think I understand now but what's the problem with building foundations + leaving space for the South platforms first while accommodating for Broadview Ave in order to only move those tracks once? Or was the original track placement in the way of doing that?
 
The active GO tracks were moved to the current location in a first phase, a long time ago, with the objective of serving customers on GO and VIA throughout the many years of building the Ontario Line and relevant GO expansion.

It always seemed smart and safety-oriented to move the active tracks (temporarily) as far away as possible (within the corridor) from the highly active construction activities. Once the new construction is finished for GO expansion particularly, the new tracks can be activated, and then the temporary tracks can be removed and the final product installed there as a final stage.

It appears the Broadview extension is not driving anything with respect to timing. I have been unable to find a public timeline for the new road, let alone the transit infrastructure that is supposed to go on it. I mean, the TTC can't bring its current streetcar fleet south of Queen without a way of turning them around. The current plan for East Harbour Station has no turning loop. Nobody knows the final plan for the buildings south of the rail corridor, which complicates building even a temporary loop.

It appears the long-term plan is for the streetcars to go south to Commissioners, but there are no tracks there either. To go from the planned foot of Broadview to the Leslie Barns via Commissioners is about a kilometre of new infrastructure. To go in the other direction (westbound on Commissioners), a bridge is missing over the new Don River outlet, and that whole idea would not make much sense without QQE being funded and under construction.

It still is highly unproductive to not have framed in the broadview extension on the east side the way they’re doing on the west side currently but that’s Public works projects in Canada… The amount of waste and duplication is mind boggling… The East side was completely in operable for nearly 2 years. It should have been dealt with… It’ would not have created any more ‘risk’ to the live rails then than it will now… Ah well… The entire project is also on its 3rd fence Installation… It’s a good time to be a Mx Contractor!

The tracks were originally located where the northern platform is currently being built, so they had to move no matter what.

But to build the southern platform first - when there was space to do so - and then move the tracks once in order to build the northern half? I suspect that the issue then becomes one of timing, and especially with the works elsewhere.

The job at Broadview is big enough that I suspect that they just didn't have enough time to build the southern part of the overpass while the tracks were on the northern half and still allow for the construction to progress elsewhere on the site. And if the tracks are located on the northern half at Broadview, but the southern half at Eastern, there may also be alignment issues with the track.

Spitballing here, but that's what makes the most sense to me.
