    This is a King County Local Services project.

    King County Road Services Division is prioritizing 244th Ave NE near SR-202 to receive snow and ice pre-treatment.

All private property owners adjacent to the trail will be able to access their property during construction with limited exceptions for safety reasons. For example, access may be limited, or neighbors may experience short delays during major material unloading or wall construction along a lane. King County plans to incorporate flaggers/spotters on site on site to help pedestrians safely access their properties during daytime.

    • Project Start Point: Approximately 1,350’ south of the intersection of SE 8th Street / East Lake Sammamish Parkway SE (STA 371+59)
    • Project End Point: Approximately 750’ south of the intersection of NE 16th Street / East Lake Sammamish Parkway SE (STA 468+00)

    The last uncompleted ELST section, the 1.9-miles from Pine Lake Creek to Inglewood Hill Road, will be closed for construction beginning in early June 2022 until December 2023.

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

    This is a King County Local Services project.

    King County Road Services Division is prioritizing 244th Ave NE near SR-202 to receive snow and ice pre-treatment. 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 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.

    Crews from Puget Sound Energy and InfraSource will be working to replace portions of the existing underground natural gas main with new, corrosion-resistant plastic pipe. Traffic control flaggers and signs will guide vehicles and pedestrians safely around the project areas and there will be lane closures and revisions as crews move along the project route.

    Gas main work in the Tree Farm Neighborhood is ongoing. Work will take place between the hours of 8:00 a.m. to 4:00 p.m.

    The gas main replacement on NE 8th St is complete. Necessary asphalt restoration should begin in late October. Work on NE 8th St. will take place Monday through Friday, 9:30 a.m. to 3:30 p.m.

    Rough Pavement Reminder: PSE’s recent gas work on NE 8th St between 228th Ave NE and easterly roundabout is temporarily covered with asphalt, but the surface is currently rough. Staff are aware of this are working with PSE to have the pavement restored to a better condition as quickly as possible. In the meantime, motorists and bicyclists are reminder to use caution when navigating the area with their motor vehicles.

    Striping and Thermoplastic Markings Maintenance Work

    The City will be performing striping and thermoplastic maintenance work on the city’s arterials throughout the summer to refresh existing fog lines, center lines, and thermoplastic markings. Thermoplastic markings include arrows, stop bars, bike symbols, and other markings in the roadway. The arterials being targeted are shown in the map below. This type of work requires dry road pavement so dry weather days are being targeted. Drivers should expect delays and use caution.



    East Lake Sammamish Trail South Segment B Stage 1 Construction

    The King County East Lake Sammamish Trail (ELST) South Segment B Phase 1 continues with construction. There will be traffic impacts related to the closure of the gravel surface trail segment which causes the re-routing of cyclists and pedestrians to East Lake Sammamish Parkway (ELSP). Additionally, there will be construction traffic on ELSP.

    • Project Start Point: Intersection of SE 33rd / East Lake Sammamish Shore Lane Drive SE
    • Project End Point: Approximately 900' south of the intersection of SE 8th Street / East Lake Sammamish Parkway SE


    Notices for construction activity outside of the City of Sammamish:


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

    This is a King County Local Services project.

    King County Road Services Division is prioritizing 244th Ave NE near SR-202 to receive snow and ice pre-treatment. 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 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.
