A little further north, it looks like the new bridge/station over Gerrard/Carlaw will be quite wide and may cover the whole intersection (photo taken from the pedestrian overpass at Pape)

I believe the Nov 15-16 weekend closure was used to relocate utilities off the poles at this intersection. The artist rendering suggests only traffic lights will remain.

Moss Park Station:
Corktown Station. Looks like they have fully knocked down the tunnel connection between the North & South pits.

I wasn't expecting this on my trip to work this morning!

It will be hilarious when Line 3 finishes ahead of Line 5.
(Chow just announced yesterday don't expect Line 5 until at least Feb 2026)

Look at the worker at the right side of the bridge and you'll get a sense that this bridge is going to be an massive presence when traveling on the DVP or walking in Corktown Common.
I passed by in my car a few days ago and was wow'd by it's size and I'm expecting the span to elevate for another 3 sections from here.

Personally I'm impressed by the consistency of bridge design around the place.
Here is a picture of a bridge over the Don River at Don Mills, which still exists (but no longer carries Don Mills) (source):
Here is the Pottery Road Bridge over the Don River from around the same time, which is still in use (source):
Now we have the new bridges in the Portlands, all shaped in a similar way (source):
And lastly the new Ontario Line bridge that's currently under construction (source)
Impressive!

Good call. The first bridge I thought of when I saw this design was the Humber Bay Arch bridge.

Just a curious question about the spoils from the tunnel boring machines as they progress along the Ontario Line route.
I know that in the case of Eglinton West extension spoils from tunnelling had to be transported all the way back to the TBM launch site to be stored temporarily until hauled away.
In the case of the Ontario Line, the stations are being excavated before the TBMs have even been assembled and begun their journey. But once they do get going, and then pass through each of the station sites along the way, why wouldn't the spoils just be removed via the open pit of the last station site the TBMs just passed through? Or, do the spoils still need to be transported all the way back to the Exhibition site for storage before being hauled away?
At some point trucks will need to be loaded up to haul away all that dirt and rock and there's obviously logistics involved with that. So, I'm thinking only the Exhibition construction site is set up for just such a purpose. But it does seem an awfully long distance to transport dirt especially once the TBMs are at the far end of tunnelling.

You greatly over-estimate the competence of Transportation Services and TPS to enforce such a thing

they use a conveyor belt system for spoils, it's not a particularly complicated endeavor nor is it particularly expensive. I imagine that the cost of running seperate spoils collection facilities at each station far outweighs the extra transport distance.
The plan is for all spoils to be managed at Exhibition as far as I know.

This one is a network arch. It has diagonal cables that criss-cross. It results in much smaller deflections which is good for railway.
The ones up top are Charles Mattaini Bowstring Arches, concept brought over from Italy over 100 years ago (and many still exist in rural Waterloo).
Humber is a pure tied arch bridge (for pedestrian loads).
The Portlands bridges are clearly designed by architects and not engineers.

Not really, I did say it was crazy. It would also require a rehaul of how we signal traffic and our confusing inadequate wayfinding systems/traffic signalling systems have already been flagged as an issue here.
