U.S. Highway 20 east of Sweet Home near Sheep Creek will be closed to through traffic from Wednesday through Friday, Sept. 8-10, so crews can install two culverts that are part of a landslide repair project.
The slide area is between mileposts 54 and 57, just west of Sheep Creek.
The three-day full road closure begins at 12:01 a.m. Wednesday and ends at 11:59 p.m. Friday.
Crews have been working on the slide area since Aug. 23, with single-lane closures and flaggers controlling two-way traffic Monday to Friday, 7 a.m. to 6 p.m. There are no lane closures at night, or on weekends and Labor Day.
The suggested alternative or detour routes during the full closure are OR 22 and OR 126.
