Beginning Monday, rock slope work east of Leavenworth is expected to slow traffic on Highway 2.
The Washington State Department of Transportation said for the next three weeks the highway will be reduced to one lane at Milepost 102 between Peshastin and Leavenworth with flaggers controlling traffic.
WSDOT is advising motorists it will mean longer than usual travel times between Wenatchee and Leavenworth.
The work is in the same area where in January of last year a mudslide struck a guardrail and partially blocked a lane of the highway.
