Highway 125 is closed on Sunday, after a mudslide blocked the roadway between Trail Creek and FS Rd. 112 on Saturday night.
The closure begins 4 miles south of Willowcreek Pass, at Mile Point 7.5, according to officials.
Delays are expected, and there is no information on when the highway will be reopened at this time.
This is the second time a mudslide has closed this stretch of road in July.
