The median of the SW ring road would make great ROW for a circumferential LRT line:
Seton (transfer with Green Line)->Somerset Station (connect with Red Line)->jog over to 162nd Ave ROW->future Providence area->re-join ring road ROW->Westhills->Glenmore Trail ROW->MRU->37th Street ROW->Westbrook Station (transfer with Blue Line)->Shaganappi Golf Course ROW and new bridge over river->29th Street ROW->Foothills Hospital->West Campus Blvd ROW->University District->New University Station->Brentwood Station (transfer with Red Line)
Who would ride a line that was that far out?
I could see in the long term the possibility of some SE (Seton) - NW (University Area) train line that basically connects all the major activity centers and institutions along the way. Although I would suggest that instead of going to Westhills, the line makes it's way over to 14 Street SW, and uses the SW Transitway so it connects with Rockyview Hosptial, then heads over to MRU. From MRU on, there's several ways you could go about it possibly. Should it stick on Crowchild, and go along 17th Avenue SW to go to Westbrook? Then from there, does it cross the river by Spruce Cliff, or head west along Bow Trail and cross the river instead at Edworthy Park?DT Commuters from the massive Providence area (if it ever fully builds out), riders headed from the deep south to the MRU area, people trying to get from the west side of the city to Foothills/U of C without going through DT. Calgary can't even get the Green Line built, so this is a fantasy. Maintaining the ROW will likely prove valuable some day. Another crazy idea would be diverting the CPR line from somewhere around Cochrane into the SW ring road ROW and then heading east along highway 902.
Also how does it go through the University area? Should it connect with Market Mall somehow? I feel this section is really based on how they want long term transit to be in that area as well. Something should be done to address the Red Line not going more west to hit major trip generators in that area. Perhaps there's an internal people mover system that it can connect with. Or would this proposed crosstown line act as the radial line for that area.
