Valley Line LRT/ Valley Line West | ?m | ?s | City of Edmonton

I think part of the challenge with the SE segment was the challenge with the CPR tracks, and other obstacles. The Gantry crane lifts smaller loads, and is more mobile. The SE line had more streets to cross (98 Avenue, Argyll, Coronet, Wagner, 75 Street, along with Whitemud Drive. Of course, there were other challenges.

Segmental erection is in general faster than cast and place, like Transed used. The quality control with segments also seem to be superior. Transed replaced the whitemud segment due to improper curing, and I believe 3 segments across the elevated portion.

Calgary used a gantry crane for their WLRT extension, which crossed over a multi track CP mainline.

That's right, I already forgot about the Whitemud replacement fiasco.....geez!

Yep. That set them back nearly a year. Pretty ridiculous how many Q.C failures Transed had.

Pictures going west from Misercordia until 178th St. It seems so much quicker than Trans Ed.

Let's hope their rebar design is correct this time considering they are using the same pier designs as VLSE.

It’s a completely different design. Parsons is the engineer on the west compared to bechtel on the southeast.

These are the new ones? Sheesh, transit needs to get some designers from the comms department to help them out. 1990s vibes

Same with the arc system design. They need to either get better designers in house or outsource this stuff. It’s terrible.

I've always thought LRT station exits should be numbered. I've found that useful when navigating foreign metro systems.

I think some bus stops at the transit centres have A, B, C,…

I think the buildings can be made more visible (colour them and identify them). I like the numbers for the exits. They would be great for first responders.

Seems like a lot to do in 2 months? Are they just getting the new road down to reopen on one side, then worrying about the LRT tracks on the other side after?
