How long did the Weber St. grade separation take?
April 2013 - December 2014, although some of the finishing touches are still unfinished, or were as of a few weeks back.

Here's an updated video from CTV Kitchener with drone footage of the actual fire (scary!) and the aftermath. It sounds like it thankfully is superficial damage that will be able to be repaired.

And Weber had to continue to operate as a through street for much of that.April 2013 - December 2014, although some of the finishing touches are still unfinished, or were as of a few weeks back.
Sadly, the forum upgrade clobbered a lot of old images, so I can't find good examples of the TTC method.
Here's the best I could find, out of the Spadina rebuild thread

Well... yes, at least as much as they now have to spend a couples weeks cleaning up, and starting again.Did the fire delay the project?

Ties now embedded in concrete, rails still exposed.
TTC place 8-12 inches of concrete base that the ties will sit on first. Depending on the line, conduit is place on the ground with the concrete being pour on it as the base. There a few inches of shims under the ties to level them.

This is the top coat further up the road that was built last year as well before the circle that I shot. Major stuff and a bitch to repair over time. I have all kinds of photos for this year and last up on site.
FWIW here's a very similar looking installation in Tucson, AZ.
I'm not an engineer but I would have thought that up here it would be different somehow, considering freeze/thaw and the use of salt on the roads. The "base layer" does look a little thinner than the Waterloo version.
Personally I always liked the old TTC cobblestone approach - hard on cars but very easy to dig up and fix. And the material was reusable.

Here is Cincinnati, Ohio: (Southwest Ohio Regional Transit Authority) SORTA New LRT Line Being Built this year and is now finish.
They are expecting their first car Oct 30 and about 6 weeks late. The line is schedule to start Sept 2016, but expecting it to be spring. Most of the overhead is in place.
I wonder if the different methods f laying track has anything to do with frost lines and or just preference. For example in Toronto they seem to put down a layer of concrete now underneath all major roads before putting down asphalt.
