To repair damage from mudslides last month, the highway through Little Cottonwood Canyon is about to be reduced to a one-lane road through Thanksgiving, with flaggers controlling traffic.
The Utah Department of Transportation says those lane restrictions will begin as early as 7 a.m. Monday and are expected to continue on weekdays from 7 a.m. to 6 p.m. through Thanksgiving.
Drivers should expect delays of 15 minutes to allow traffic in the opposite direction to pass. Also, wide loads over 11 feet are restricted and must contact the project hotline at 855-663-6800 to coordinate access.
Crews are removing large amounts of debris, rocks and mud along the road, and are repairing adjacent slopes. They also are repairing or replacing ditches and culverts to help channel water under the road, and are replacing numerous guardrails and signs.
Also this weekend, State Road 201 in western Salt Lake County is closed between its junction with Interstate 80 and State Road 202 near the Kennecott smelter. The road is scheduled to reopen Monday at 5 a.m.
During that closure — which allows repairing storm drains — drivers will be detoured via State Road 202 to I-80.
