CHIMACUM – A 25-mph speed limit and one-way alternating traffic is in place on state Highway 19 between Chimacum Road and Swansonville Road until further notice.
The closure is due to scouring underneath the roadway, the state Department of Transportation said.
The southbound lane is closed around-the-clock as a precaution until repairs are developed and implemented.
Geologists have been to the site to evaluate the situation, but DOT does not yet know how long repairs will take.
Travelers can expect congestion approaching the lane closure. DOT has reduced the speed limit from 50 to 25 mph approaching the site on Highway 19 from milepost 7.54 to 7.86.
A temporary signal is in place controlling one-way alternating traffic using the northbound lane.
