Hwy 1 will be fully open east of Golden for the May long weekend Between April 12 and May 14, the Trans-Canada Highway (Hwy 1) was fully closed east of Golden due to major construction on Phase 4 of the Kicking Horse Canyon Project. During that time, anyone driving between Golden and the BC-Alberta border has been forced to detour through Radium Hot Springs via Hwy 93S and Hwy 95, adding 90 minutes of travel time. This past weekend, the highway fully reopened to traffic for the first time since construction began, but has since closed again for weekday construction. It will be fully open to traffic once again for the May long weekend, starting at noon on Friday until noon on Tuesday, May 25.
