A former section of Highway 1A exists along the former Kicking Horse Trail, the original road between Lake Louise and Golden, British Columbia that opened in 1926. When the Trans-Canada Highway was realigned in 1962, the segment became Highway 1A. It began at British Columbia Highway 1, west of the Alberta border in Yoho National Park. It meandered eastward through Kicking Horse Pass to Lake Louise, generally paralleling the main Highway 1 and CPR rail line to the south. The section between Lake Louise (townsite) and Lake Louise (lake) is known as Lake Louise Drive, while the remainder of route is now closed to vehicle traffic and is part the Great Divide hiking trail.
