Right now, the only remnant is an AB 1A shield on EB 14 Ave NW approaching the 14 St NW interchange near SAIT.

Does anyone know when that section would have been decommissioned?
Off the top of my head, I think that a 1A route through downtown would have been abandoned as a highway in the late 1950s, when the Trans-Canada was built along 16th ave.

The map below is from 1926, and shows in red the route you are describing. It used 10th street rather than 14th street north of the river, as the 14th street bridge wasn't built until the mid-1950s.

EDIT: It's entirely possible, probable even, that the 1A remained in use on central roads long after the 1 opened to serve as an alternative... I might look into that.

I think it was in the early 90's, but not positive.

Thanks! The sign I was referring to is at https://goo.gl/maps/HpUdCuF9zEx.

Yep. Other signs in the area you can tell were repainted to remove the 1A shield (for instance https://goo.gl/maps/RJM2KXKaATq) so I'd guess that one simply was overlooked.

Actually, now that I think about it, the 1A designation would have been CREATED in the late 1950s with the coming of the new No.1, NOT removed. I don't know what I was thinking. Ignore my post.

Also, the most recent I have found is a map from 1975 that clearly shows the downtown portions as 1A.

Highway 22 from Highway 8 to Longview

Another driving video from me. Driving on Alberta Highway 22 (The Cowboy Trail) from the roundabout at Highway 8 through Redwood Meadows, Bragg Creek, Priddis, Turner Valley, Black Diamond and finally to Longview.

Cochrane Interchange (Hwy 1A/22)

Alberta Transportation announced some major improvements in Cochrane:

Quote:
Cochrane Interchange

Budget 2017 includes funding to begin the process for building an interchange at Highway 1A and Highway 22 in the Town of Cochrane...

Project Details

The project is estimated to cost between $40 to 50 million. It will include:
  • Twinning of Highway 1A under a twinned Highway 22 structure;
  • Construction of a twinned Highway 22 bridge structure over the CPR mainline;
  • Ramps to access both Highway 1A and 22; and,
  • Highway 1A bridges over Big Hill Creek.

Project Timelines

Selection of an engineering consultant will begin in 2017. Once design and engineering are complete construction could begin as early as Fall 2019, and is expected to take about two years to complete construction. Once the design process is complete, a more detailed project timeline will be available.
http://www.transportation.alberta.ca/6056.htm

Admittedly I don't live in Cochrane, but I'm a little surprised about an interchange. I know the intersection needs upgrades, but I thought twinning and dual turn lanes would be enough. The topography would be similar to the John Laurie Blvd & Shaganappi Trail intersection. Any thoughts?

I don't live in Cochran, but I'm through the intersection a few times per year.

I am glad that AB Transportation is going straight to interchange rather than the natural progression. The progression from minor intersection to major dual turn intersection only makes sense when there is a major developer that can have road improvement levies assessed against the development (essentially developer pays for 1/2 the intersection improvements). In this instance the SE and SW corners are developed and the NE corner cannot be developed due to the escarpment. The NW corner could not take the entirety of road improvement levies and remain commercially viable compared to other locations.

The other nice opportunity for highway 1A is the closure of a lot of the intersections to downtown. Only Centre Ave and 4th Ave need to be intersections. the rest (2nd, 3rd, 4th) can be closed off to improve traffic flow. This will have a further consequence of making 1st and 2nd streets much more pedestrian friendly.

I also commend Ab transportation for their insistence on going directly to interchanges. This is a intersection of two major provincial highways and therefore interchange is warranted.

Way overdue and badly needed, it's a shame it will be at least another 5 years before anyone can drive it. In the meantime they continue to add to their own problems, there are now other sets of lights along 22 going through Cochrane. Not sure why towns or the Province never seem to learn and keep doing this.

I grew up in Cochrane, and definitely its needed 10 years ago.

The constraints will make it interesting, reportedly from family that still lives there there are mixed feelings about it. The CP tracks can't be moved, which limits the design to some odd-ball designs. Some initial ideas floated (but not from the province) involve some massive loop ramp bridge structures and essentially lowering 1A below 22.

There also sounds to be a bit of a political issue as well from some people that the timing for this is a "vote NDP in '19 and we'll build it, as the conservatives will cancel it" project.
