So here’s the skinny on the fuckery that’s been going on with the Green Line in Calgary. It looks like they’re finally coming to a conclusion and may actually be able to begin hard construction on time (Summer 2021). I don’t personally support their conclusions (mostly just butthurt about losing the tunnel under the river), but I do understand the financial and geological limitations of a city our size and geography in the economically austere climate we are in.
- The tunnel under the river is out the window for good due to the extreme depth of Eau Claire and 7 Avenue SW Stations and extremely poor soil conditions making it cost prohibitive even when not considering the depth
- 4 Street SE Station is now underground and 1 block south of previous alignment, to be better connected with new Flames Arena and Stampede Park
- Eau Claire Station will now be at grade; the city is in consultations with Harvard Developments to integrate the station into the Eau Claire Market redevelopment
- The downtown tunnel will begin between 2 and 3 Avenue SW (a block south of Eau Claire Station)
- There will be a new bridge built between Eau Claire and north of the Centre Street Bridge.
- The downtown subway (including 4 Street SE, Centre Street South, and 7 Avenue SW stations) will connect to Eau Claire Station at grade, then progress on to the bridge
- Ninth Avenue North (Crescent Heights) Station is back in play as a grade level station, though not a certainty
- A decision on whether 16 Avenue North Station will be underground won’t be released for a couple months
- The southeastern portion of the line will remain as was already planned and designed.
Some new concept renders of the revisions…
Crescent Heights Station
Side traffic version
Centre traffic version
Eau Claire Station
Tunnel Portal Concept – Options being considered are a staircase up to the +15, or a performance space with plaza.
Centre Street North – between Crescent Heights and 16 Avenue Stations
Bridge options being considered
Overall, it’s not the worst compromise given the constraints. Here is the layout of the changes; green is new alignment, yellow is 2017 proposed alignment. It is unclear if the bridge and Centre Street portions will be built in Stage 1, but we will know by April, around the time of the decision on the 16 Avenue Station being underground or not. I’m really just glad that most of the decisions are finally made and we can move the f*ck on with detailed design and construction.
