Construction Set to Begin on Upper Mill Creek Canyon Road Improvement Project in May

Trails to remain open during project; winter recreation access to be preserved

Salt Lake County, UT — Salt Lake County, in coordination with the U.S. Forest Service and the Federal Highway Administration, is announcing that construction on the long-planned Upper Mill Creek Canyon Road Improvement Project is scheduled to begin on May 1, 2025, with bridge work at the Elbow Fork area starting before May 1.

The project, funded through the Federal Lands Access Program (FLAP), will address roadway safety concerns, improve drainage and erosion control, and enhance long-term access for canyon visitors. During the winter, the roadway above the Winter Gate will be groomed for winter recreation.  

Throughout the 2025 and 2026 construction seasons, there will be no motor vehicle or pedestrian access on the roadway beyond the winter gate. However, trails—including the popular Pipeline and Upper Pipeline trails—will remain open and accessible. These trails will serve as key routes for hikers and bikers navigating the canyon during the project.

Construction is expected to continue through Fall 2026. Visitors are encouraged to plan ahead, consider carpooling, and consult project and trail maps before heading into the canyon.

More information about the project, including maps, anticipated schedules, and visitor guidance, is available at slco.to/FLAP.
