Road maintenance on 244^th Ave NE near Redmond Fall City Rd, (SR-202)

This is a King County Local Services project.

King County Road Services Division is prioritizing 244^th Ave NE near SR-202 to receive snow and ice pre-treatment. Due to a slide occurring in winter 2020, both lanes of 244^th Ave NE are narrowed until the impacted support wall can be repaired. The repair of the support wall is expected to begin in Summer 2023. Soil samples yielded unexpected data, which caused the design phase to be extended. King County Road Services Division has a 24/7 Road Helpline - (206) 477-8100. More information on this project can be found linked here.
