Hopefully 2 more weeks of progress can be made before the winter stoppage on the guideway!

I don’t see why they won’t keep working through the winter on it. When Calgary used a gantry they continued to lift over the winter

I need to move tf out of Icon before this spring, 102 closure for 2025 + Beaver Hills/Michael Phair construction is going to make alley access a freakin' absolutely nightmare. And sounds like the Saturday market is then going to have to run at reduced capacity, assuming they'll only have vendors from Michael Phair to 102 to accommodate access.

The market can expand north of 102 Avenue intersection (which will remain open) and is exploring other options as well, as vendor demand for next year is very strong.

I think the Gantry crane was making progress eastward last winter.

Don't we mean Westward?

Don't we mean Westward?

No. This winter westward

Sorry for confusing everyone.

The article below from last December had Marigold indicating that they should be finished with the Gantry system at the end of this year and then dismantle it early in 2025. Is that going to be the case or are they shutting down for this year once they build the sections over the WEM parking lot? If its the latter, what happened to not have all the overhead sections in place? I know why TransED would not post much but do we know how the progress is with the Valley Line East? Are they hitting their milestones?

The gantry cannot run during the winter (last year was the same).

Not sure if snow or a certain degree below 0 is what determines the shut down exactly, but that’s what marigold has said previously.

I'm guessing it's an issue of the gantry not being designed to (safely?) function in Edmonton's winter conditions, considering it was originally built for a project in Dubai. Can't imagine it's an issue of joining the precast guideway segments in the cold.

I always go back to this video for my reasoning:

Seems like it’s pretty cold when they were erecting them in Calgary, Deal also made that gantry crane so I assume it’s the same hydraulics.

Also the reason they shut down last year was because they had to erect the segments between the straddle beams by crane and temporary supports.

Just my opinion though

I wonder if part of it has to do with post-tensioned cables. If they contract in winter, they would be slightly longer in summer.

I called Marigold today, and they said that their plan is to re-open the north lanes soon, keep both sides open for the winter, then close the south side next spring to re-build it, and then work in the centre on the actual lrt infrastructure. They anticipate a couple more years of "heavy construction work" at this point. They originally intended to re-open the north lanes tomorrow (October 31) since that's the usual end of the construction season, but going by the forecasts they're now planning to go until mid-November. They're pushing to complete as much of the permanent infrastructure as possible, and minimize the amount of temporary roadwork that'll have to be replaced later on.

Speaking of temporary infrastructure, I noticed that it appears as though they paved over some of the new curbs along the north side of 104 Ave, to accomodate entrys/exits from the Brewery District. Can the asphalt be chipped off later on without damaging the curbs, or will those curbs need to be replaced?

They can mill the asphalt to remove it. Also thanks for the info!
