Here's a new video from ML showing the elevated line construction
(not being a construction engineer....) The erection of the pillars seems fairly efficient and straightforward, but I'm struck by the amount of effort and scaffold erection to pour the spans. Is this a normal/preferred technique?
Probably I'm spoiled by the beauty of the more complicated method used to place the pre-cast spans on the Davenport flyover.... is Eglinton West a siimpler/ more ccommon process, or is it extreme?

It was concluded, earlier in the thread, that the profile of the bridge changes too many times, as well as curving along Eglinton Ave, for it to make sense to use pre-casting or to attempt balanced cantilever construction (see Westey's post on that in the Ontario Line thread). The cross section of the bridge varies (W to E): 2 isolated bridges, transition, 2-track width bridge, transition, 3-track width bridge, 2 isolated bridges.

Well, ok, it has been raining heavily…. But in a newly opened station, this isn’t encouraging.

Wrong thread, but part of the issue is that these stations don't have forced air circulation so its hard to dry up moisture.

It's actually not the rain that's the issue there, it's the humidity. And it's a problem at many of the underground stations.
It doesn't help that the tiles get fatally slick with the moisture, either. That ramp in down that hallway is downright dangerous.

Hmm ... what's the difference that causes this in these new stations compared to the un-airconditioned Line 1/2/4 stations?

Give them a few decades and some stalagmites and stalactites may form in the passageways and stations. (If there is some limestone above them.)
