With the current work on 16th Avenue in Calgary there was some discussion about changing the designated Trans Canada Highway route through the city. Out driving on the weekend I came from the east city limit heading west on McKnight - John Laurie. I think this is a realistic option to turn into a free-flow TCH route as far as Sarcee Tr NW at which point it would have to head south to Crowchild (Hwy 1A) or further south across the river to link up with 16th Ave (not very likely). New connections to the TCH outside the city limits would be required but not insurmountable. I like the fact this route would pass close to the Airport, and there are some great views of the skyline, mountains, and the city which would leave a good impression on travelers. Widening and interchanges for John Laurie would be relatively simple along Nose Hill park.
If I was more software savy I would post a map, but sorry, I'm not. Feel free to do so for your proposal. Have fun with it.
