Big Cottonwood Canyon Wildfire Mitigation Project

Beginning in May 2022, Rocky Mountain Power will begin construction in Big Cottonwood Canyon and will make improvements to overhead power lines to mitigate wildfire threats along State Road 190 (S.R. 190).

This project will replace segments of overhead power lines along S.R. 190 with underground conduit and upgrade existing overhead systems to withstand weather and environmental conditions to help prevent wildfires, protect communities and provide safe, reliable power. 

Crews will be working Monday through Friday from 7 a.m. to 7 p.m., with minimal night and weekend work. Construction is anticipated to last through late August 2022.

Construction schedules are weather-dependent and subject to change.
