Partner: Rocky Mountain Power
Status: Phase I begins April 7, 2026
Location: Kearns Boulevard, Woodbine Way, Bonanza Park area, Boot Hill
Park City Municipal is partnering with Rocky Mountain Power to underground high-voltage transmission lines that currently run overhead through the Bonanza Park area, along Boot Hill, and adjacent to the Park City Cemetery.
Undergrounding the lines will add available cemetery plots, reduce wildfire risk, eliminate transmission towers from the area's view corridor, and remove a 60-foot aerial restriction that has limited redevelopment options on the Bonanza Park 5-Acre Site.
The project is scheduled over two phases:
Phase I (Spring 2026 to October 2026)
Work on Kearns Boulevard is scheduled to begin April 7, 2026 and will continue through mid-May. Drivers should expect traffic impacts during this period.
Schedule:
- April 7-12: Traffic control on Kearns Blvd. One lane of eastbound traffic will be maintained. Westbound traffic will be diverted at the intersection of Kearns Blvd. and Bonanza Drive.
- April 13-17: Traffic control on Kearns Blvd. One lane of westbound traffic will be maintained. Eastbound traffic will be diverted at the intersection of Park Avenue and Kearns Blvd.
- April 20-May 15: Kearns Blvd. will carry one lane of traffic in each direction from 7:00 a.m. to 4:00 p.m.
