Hey, how's that Valley Line LRT construction coming along? ;)

Walked by there a couple nights ago to see. I neglected to take photos, but the only thing left are the abutments and stubs from the old columns.
I’m absolutely enthralled with the fact that they went through so much trouble to keep access to Fireball (a random little MTB trail that appeared there last spring) open through the bridge site. The attention to detail on that is refreshing compared to Transed’s closures.
I think the Groat sidewalk is still closed, but there is quite the cowpath on the west side going down next to the bridge to access it. I think it’s fair game to use that, until construction work starts up again.
 
Thanks for the update.

Shame that bridge had such a short life, too bad they couldn't just add in a new bridge, even though the salesmen err consultants promised they would be keeping the brand new bridge...

Why it takes 800 days is another story, couldn't some form of pre-fabrication be employed?
 
Well @Habibfazil I'm no expert on bridges by any stretch of the imagination, but the reasons why they need to demolish the Stony Plain Road Bridge for a new one may be due to the old bridge being near the end of its lifespan, the need to build two LRT lines and a MUP in addition to the existing road and sidewalks, weight restrictions, having to acquire or expropriate adjacent property for a new bridge, and overall cost.

I think you are maybe confusing the 102 ave bridge, which was recently replaced, with the Stony Plain Road bridge, which has been removed for this project and was closing in on requiring replacement anyway.
 
I wonder if they will purposefully allow rapid deformation of the beams to form that curve and simultaneously act as the 1% of public art (sculpture).

I sure hope bridge-itis is not contagious and the new bridge will not catch this ailment from its neighbouring bridge immediately to the south.
 
Here’s a pic at Wagner Road. Some of the piers are showing the concrete work and repairs:

Not at all, 102nd was done in the past few years.

Stoney Plain road was done about 10-15 years ago, around the time the city discarded the old trolley coach network.

At the public information meetings the new tram line to the west showed tracks and only 2 lanes of traffic. They were asked if the bridge fairly new bridge needed placement, and no. Of course they also mentioned they could tuck away all the overhead vs that trolley coach overhead...

The Stony Plain Road bridge over Groat Road might have been rehabbed 15 years ago, but that bridge was not replaced it turns out. I'll be damned, because I thought it was and I seem to recall the talk of just running the trains on the existing bridge. I seem to even recall the shuttle bus that was used.

So... I went digging.

"It is unknown, at this time, if the existing bridge contains any hazardous materials but since the bridge is more than 50 years old and contains embedded communication conduits, the bridge will be tested for asbestos and other hazardous materials content prior to demolition and if containing hazardous material, will be handled and disposed accordingly"

So it was indeed older than 50 years back in 2018.

By March 2011 the talk was a new bridge over Groat Road.

Edit: The refurbishment was in 2013 and cost $4 million.

Yeah, the current (or former, I guess) Stony Plain Road Bridge was surprisingly old. I never paid it much mind, just thinking it was from the '60s or something. However, it turns out work on the crossing started in 1953 in preparation for the construction of Groat Road. A simple ravine-fill previously allowed traffic to cross the gulch. From the minutes of City Council, May 11th, 1953:

And the fill in 1948 and bridge in 1957, respectively:

Thank you for the information about the bridge being rehabbed vs new, I stand corrected 👍👍👍

Guess this makes sense for replacement, but 800 days, can't fathom that timeline. Here's hoping we don't see more Montreal style concrete work 😉
