It appears that the twinning will be extended to Hwy 22.
1A - E of Hwy 22 to W of Hwy 766 Twinning - Grade, Base, Stage Paving 6 [km]
Contract for 2010 & 2011 Construction
1A - Major Intersection Improvement @ Jct Hwy 1A & 22
Intersection Improvement
1A - Bighill Creek Bridge on Highway 1A, at N Boundary of Cochrane (521-1)
Structure Replacement
1A - Hwy 22 - E of Hwy 22 Twinning - Grade, Base, Stage Paving 4 [km]
22 - CPR Overpass on Highway 22, at W Boundary of Cochrane (77466-1)
Twinning - Structure
This is from the 2011-14 Major Construction Projects. The 4 km from Hwy 22 to the current twinning as well as the Hwy22/CPR Overpass twinning is new.
I would like to see an interchange at 1A/22 but I think the budget deficit precludes this.

Unfortunately, it doesn't show the configuration of 1A on Cochrane Hill.

I originally posted this in the Calgary/Stoney Trail thread but decided to re-post it here as it has little or nothing to do with Stoney Trail.
If you want to see what the 1A might look like thru Cochrane, check out:

As for twinning on Cochrane Hill, I would imagine that would involve a lot of retaining walls, but that is just speculation on my part.
This shows the planned interchange locations between Calgary and Cochrane:

If anybody regularly travels between Calgary and Cochrane and can get some pictures of the current construction, they would be greatly appreciated. I haven't been out to that area for about two years. Still waiting for the Glenbow Ranch PP to open up.
