Cyclists and pedestrians using trails along state Route 224 are being detoured around active construction zones as High Valley Transit builds its $110 million Bobsled Express bus rapid transit line.
The McLeod Creek Trail on the east side of SR-224, between Fox Point Circle and Cutter Lane, is closed for approximately three weeks, according to KPCW reporting on Monday, July 20. The Millennium Trail on the west side of SR-224 is being rerouted via Bear Hollow Drive to Cooper Lane (Frostwood Trail) to Canyons Drive.
High Valley Transit posted an interactive ArcGIS map on Thursday, July 23, to help trail users find their way around the closures. The map is available at experience.arcgis.com/experience/eaa5009b228340a794cbccac52b5de26.
"We do want to emphasize the importance of following all the marked detours and closures, really focusing on our cyclists and pedestrians," High Valley Transit Chief Development Officer Gabriel Shields said on July 20.
Signal upgrades at Park Avenue and Deer Valley Drive
Crews also started upgrading traffic signals at the Park Avenue/Deer Valley Drive intersection on Monday, July 20. High Valley Transit is building dual left-turn lanes from SR-224 onto Deer Valley Drive and dual right-turn lanes from Deer Valley Drive onto Park Avenue. UDOT's Wasatch Back office confirmed police officers are directing traffic at the intersection during the signal work.
Shields asked drivers on July 20 to watch for uniformed officers and obey reduced speed limits in the work zones.
Overnight utility relocation is also underway at the Silver Springs Road and Old Ranch Road intersections with SR-224, running from 7 p.m. to 6 a.m. Silver Springs residents must head north to Silver Springs Road during those hours; the Old Ranch Road detour uses Cutter Lane and Split Rail Lane.
What the project delivers
The Bobsled Express, officially named in April 2026 according to the Park Record, will run free bus service every 10 to 15 minutes between Kimball Junction and Old Town Park City on low-emission vehicles. In the county portion of the corridor, buses will use dedicated lanes; within city limits, they'll share mixed-flow lanes with cars. Shields said in March 2025 that the system will cut the Kimball Junction-to-Old Town trip to a little over 15 minutes.
High Valley Transit secured $66 million in federal grants toward the project. The total price tag now stands at $110 million, according to KPCW, up from the $90 million estimate cited in March 2025. Full construction on SR-224 began in April 2026 after preparatory utility work started in fall 2025. Completion is expected by summer 2028.
The Park City Council voted on Thursday, June 4, to donate approximately 0.07 acres of Redevelopment Agency property at 2060 Park Avenue to UDOT for the BRT project, according to KPCW. The parcel was appraised at approximately $481,000.
Construction paused for Pioneer Day on Friday, July 24, and resumed Monday, July 27. In August, UDOT crews will repave SR-224 from the Marsac roundabout to Kearns Boulevard overnight over about a week.
