Sahalee Way, from NE 8th to State Route 202 

Turning movement traffic counts will be collected along this corridor from February 26 – March 1. Drivers may see temporary cameras and traffic tubes collecting traffic data at intersections as part of the Sahalee Way Corridor Study.

Pedestrian Signal Revision

The city has made signal revisions at several locations on 228th to reduce wait times and improve pedestrian mobility. These revisions will allow left turns to happen while yielding to pedestrians crossing north-south. The city will analyze intersections and selectively implement this at locations where pedestrians experience frustratingly long wait times.

The first intersections scheduled for this change are 228th and E. Main St. and 228th and NE 12th. New signage will warn drivers to yield to pedestrians when turning left.

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

This is a King County Local Services project.

Due to a slide occurring in winter 2020, both lanes of 244th Ave NE are narrowed until the impacted support wall can be repaired. The repair of the support wall is expected to begin in Summer 2024. 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.
