Traffic Management

It is well-known that the remaining two-lane canyon section of the Trans-Canada Highway is severely constrained. As a result, the final phase of the Kicking Horse Canyon Project to improve safety, widen and realign the highway will inevitably require traffic disruptions and, at times, full highway closures. The traffic management strategy is designed to minimize and mitigate traffic disruptions while allowing the work to proceed safely and on schedule.

The first extended closure (requiring motorists to use Highways 93 and 95 as an alternative route) will occur from April 12 to May 14, 2021. See Construction/Traffic Notifications for details.

From Winter 2020/21 through to Winter 2023/24

As a rule of thumb, the contractor will be required to abide by the following during the course of the project:

Summer

  • During daytime, the highway through the Canyon will remain fully open and free of interruptions, other than momentary traffic control for turning vehicles.
  • Overnight, interruptions may range from 20 minute stoppages to 8 hour closures. The closures will require significant advance notice.

Fall, Winter and Spring

  • Daytime may see stoppages from 20 minutes to 2 hours.
  • There may be closures of up to 10 hours overnight, which will require significant advance notice.
  • In addition, there may be multi-day extended closures from April 1 to the end of May and from mid-September to the end of November.
  • The highway will be kept open for Easter and Thanksgiving long weekends, and there will be two daily peak-hour windows to allow passage for school buses, commuters and other essential local traffic/trips. Extended closures will also require significant advance notice, and the first is now expected to occur in spring 2021.

During any closure travellers would have the option of taking the alternative route using Highways 93 and 95. By limiting extended closures to off-peak periods, the total combined traffic volumes on the alternative route will be comparable to the peaks that Highways 93 and 95 currently experience in the summer.

Further information on the evolving traffic management strategy was presented at public information sessions in Radium Hot Springs on October 29 and Golden on October 30, 2019. See pages 11-25 of the displays for details (PDF, 31.5MB).
