Mt. Superior Avalanche Mitigation Project 

July 8 - October 2024

WHAT/WHY: UDOT will be installing Wyssen Avalanche Towers, a type of Remote Avalanche Control System (RACS), in Little Cottonwood Canyon (SR-210) on the Mt. Superior ridgeline above the road. This project will help UDOT transition away from the P-Ridge Howitzer that has been used on the south side of the canyon, shooting over the road and buildings in the Town of Alta. Wyssen Avalanche Towers are operated remotely, allowing for more efficient and safe avalanche mitigation for workers and the public.

Construction is expected to start as soon as July 8, 2024 and estimated to be complete in October 2024.

WHERE: Mt. Superior in Little Cottonwood Canyon (SR-210). See the map of the installation area below. 

  • 16 Wyssen Avalanche Tower installation locations 

  • The shaded area shows where the area is closed to all recreation through the duration of the project (October 2024)

  • Equipment will be staged in the Wildcat parking lot


Project Duration: July 8, 2024 - October 2024

Work Hours: Sunrise - Sunset

Workdays: Up to 7 days a week including holidays, weather permitting

Schedules are subject to change due to weather conditions. 

No road impacts below the Town of Alta are expected, however, intermittent road closures may occur on the mainline below Mt. Superior. The Bypass road will remain open to use as an alternative. 

Area closure is for the duration of the project due to helicopters transporting equipment directly over trails and recreation areas.

For your safety and ours, please respect all closures.
