Where did you intend to camp in BC just before the day you plan to travel into Alberta ?
This makes a difference.

The closest campground to the Alberta Border is the
*Yoho National Park Campground* at Field.

We really don't have anything you are talking about on HWY #1.
You will have to go down Hwy# 66 ( Kananaskis) or Hwy #22 through Bragg Creek ( Kananaskis ).

Did you Plan to go right into Calgary or get close to it ?

Hwy #22 goes right to #3 just East of Coleman AB.
