Big Cottonwood Canyon wildfire mitigation project

Construction has resumed in Big Cottonwood Canyon to continue improvements of overhead power lines to mitigate wildfire threats along State Road 190 (S.R. 190).

This project is replacing segments of overhead power lines along SR-190 with underground conduit and upgrading existing overhead systems to withstand weather and environmental conditions to help prevent wildfires, protect communities and provide safe, reliable power. 

Construction is anticipated to be completed by the end of October 2023.
