Cottonwood CanyonS Summer 2020 Construction

PROJECT HOTLINE NUMBER
For questions about the construction projects going on in the Cottonwood Canyons for summer 2020, call the public information project hotline at 888-420-1555.

Construction Projects in the Cottonwood Canyons:

With the multiple construction projects occurring in Little Cottonwood Canyon (S.R. 210), travelers should expect moderate to major delays throughout the canyon. Due to safety concerns, cyclists are strongly advised to plan alternate route during the construction working hours for all Little Cottonwood Canyon projects: Monday through Friday during daylight, starting as soon as 6am. Safety hazards include narrow lanes and shoulders with construction traffic traveling in both directions throughout the day, open trenches and a 24/7 temporary signal in the Emergency Mudslide Repair and High-T work zones where it is unsafe for cyclist traffic to be in line ahead of motorist traffic.

Cyclists and pedestrians traveling in Little Cottonwood Canyon should take caution in work zone areas and obey all flagger and traffic control directions during construction work hours. These directions may include walking bicycles through short sections of the work zone and/or no access as needed.

The paving project in Big Cottonwood Canyon (S.R. 190) will be in complete in September, at which time the whole canyon will be open to cyclists again.

Construction schedules are subject to change due to weather, project conflicts, utility issues or equipment/supply issues.
