Traffic Restricted in Little Cottonwood Canyon Through November for Repairs

Updated on

Drivers are urged to plan for lane restrictions on S.R. 210 in Little Cottonwood Canyon starting Monday, Oct. 7, as early as 7 a.m. The highway will be reduced to a one-lane road, with flaggers controlling traffic both up and down the canyon, to allow crews to continue repairs and make improvements in response to recent mudslides.


These restrictions are scheduled from Monday through Friday, 7 a.m. to 6 p.m., through Thanksgiving. Drivers should expect delays of up to 15 minutes while they wait for traffic to pass.


As part of this project, crews will remove large amounts of debris, rocks and mud from along the road, and repair adjacent slopes. In addition, they will clear out and repair or replace ditches and culverts, and install three new five-foot-diameter concrete pipe culverts to help channel water under the road. Crews will also replace various smaller features damaged in the slides such as signs and guardrail.
