NE 124th Street slide - Information page
On February 16, 2017 a slide occurred along NE 124th Street near Highway 203. The roadway is located south of Duvall and is a sole access road for approximately 100 residences.
The slide is about 100 feet in length and is on the valley or downhill side of the road. About half of the road is undermined. A large section has completely failed. Road crews have diverted water to help reduce the risk of losing the road, but there is still potential for road failure if the area continues to receive rain, as the ground could become supersaturated and have additional washouts or failures.
NE 124th Street near Duvall restored to two lanes following slide repairs, five days ahead of schedule
NE 124th Street near Highway 203 and Duvall has been restored to two lanes following slide repairs. The county's priority was to maintain emergency access for the community. Crews worked 10-12 hour days, six days a week, to reopen the road. Additional future work includes county crews installing plantings and Frontier Communications performing pavement repair on a fiber optic cable patch in the roadway. This work has not been scheduled yet and will not require the road to be closed.
This week crews are completing ditch work, cleaning up and removing equipment. Flaggers will direct traffic through the work zone from approximately 7 a.m. to 3:30 p.m. During the remaining hours of the day and overnight, both lanes will be open.
Crews plan to pave on Monday, April 10 and move traffic to the newly paved lane Monday and Tuesday. Note: The paving work is weather dependent. Crews also plan clean out the roadside ditch and demobilize, and hope to finish the repair work by Saturday, April 15.
Crews have put 2,000 cubic yards of rock in place to stabilize the bank. They will continue placing rock this week.
