Thanks for all the kind words. You look at Calgary in 1951 and suddenly understand how certain bottlenecks were already set in stone. No city planner would have been planning for the million plus people we have today; it would have been very far forward thinking about 500K in the city at that time of 129K.
You can see that the construction for the new highway 1 on 16th Ave is just beginning at this point at Barlow & 16th. 16th Ave TCH, would have seemed to be all that would ever be needed and a huge improvement over 17th Ave/9th Ave/10th St/16th Ave/Banff trail route!
What also struck me is how comparatively ugly the city would have been at the time. I'm sure other cities were similar - rail yards and industrial along several prime river locations in town. Expectations were different then.
You would think that only in the age of satellites and jet planes that anyone would have thought to write anything on the roof of their building. But even in 1951 when flying was expensive and a lot slower, you can find an arrow pointing to "
Calgary 2 M" on top of one of the tanks at the Lynwood Ridge refinery.
At that point, there was no confusion - Edmonton Trail really did go to Edmonton. What I didn't know is that a rail spur line went to the McCall Airport. At least the earth works continued off into the NE ending around Stoney and 64th. I assume it served the air force during WWII, but the only thing I can think of for a NE spur is a temporary line to bring in fill for the airport. The line isn't even listed in "Lines of Country: An Atlas of Railway and Waterway History in Canada", so it might have been very ephemeral.
1951 also marks the transition from building grid streets to curvilinear. You can see the new houses in Renfrew and Currie Barracks going up with curvilinear streets. It's hard to believe that some of these houses have already been torn down for infill. Speaking of the military, you can see at this time it had a huge impact on the Calgary economy. The buildup is just about at it's zenith and would already be declining in areas like McCall field.
I still have one mystery development I have no idea what it is - the patch small houses and slightly larger sized buildings north of 17th Ave NE, in fact the scar remaining from that development is visible to the present. Motor park perhaps?
