Month-long closure of Hwy 1 between Golden and the BC-Alberta border begins Monday Starting next week, the trip between the BC Interior and Alberta will get a little bit longer. Major construction on Phase 4 of the Kicking Horse Canyon Project will get underway on Monday. That means the Trans-Canada Highway (Hwy 1) will be closed between Golden and Castle Junction, right around the BC-Alberta border, will be closed for over a month. Once the scheduled closure wraps up on May 14, there will still be 24-hour closures on weekdays for the remainder of the month, with the exception of the Victoria Day long weekend.
