A “big glob” of dirt about eight feet deep and three feet wide has slid onto Highway 202 outside Redmond.
The State Patrol has shut down a stretch of the road and is assessing whether more material is likely to fall, spokeswoman Julie Startup said.
The landslide occurred at about 7 p.m. near the intersection with 267th Avenue Northeast, near Ames Lake. One car went into a ditch as a result, but there were no injuries.
The dirt is only blocking the westbound lanes, but “unstable embankments threaten the entire roadway,” according to a news release.
Motorists coming from the west are being diverted at 264th Avenue Northeast, while motorists coming from the east are being diverted at Tolt Hill Road, Startup said.
