    FOR WINTER WEATHER UPDATES, PLEASE VISIT THE CITY OF SAMMAMISH SNOW UPDATE.


    Tree Branch Removal

    The City of Sammamish is removing some dangerous tree branches along 228th Ave SE. The limits of this work are the southern City Limits to SE 35th St, near Pine Lake Middle School. Flaggers will be present in the area of work. There will be a few full road closures to allow the larger tree limbs to fall without causing damage. Work will take place from 9:30 a.m. until 2:30 p.m. Drivers should expect delays and use caution. See below for a map, areas of work are indicated in green.



    Traffic Signal Work

    Through mid-February the Sammamish Traffic Signal team will perform routine maintenance on all of the signalized intersections in the city. This maintenance will cause intersections to temporarily flash, but in some cases may cause short-term dark signals (i.e. no green, red, or yellow signals).

    Drivers should use caution and remember that a flashing or non-functioning intersection must be treated as an all-way stop. After stopping, the driver shall yield the right-of-way in accordance with Washington State Law, RCW 46.61.183.


    Sewer Force Main Project on East Lake Sammamish Parkway

    The Sammamish Plateau Water and Sewer District started a sewer force main project on East Lake Sammamish Parkway near Big Block Brewing in early November. The limits of this work are SE 33rd St and SE 37th Pl. Work hours are 7:00 a.m. - 4:00 p.m.

    The speed limit will be legally reduced to 25 mph during this project in this area. Variable message boards are in place to the north and south of the area of work. Drivers should use caution and expect delays.


    East Lake Sammamish Trail South Segment B Stage 2 Construction

    This is a King County Trail Project

    The King County East Lake Sammamish Trail (ELST) South Segment B Phase 2 will begin construction in Spring 2022. 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.

    For additional project information, please visit the project website: www.kingcounty.gov/eastlakesammamishtrail. You may also contact the project team directly by email at ELST@kingcounty.gov or by calling the project hotline at 1-888-668-4886.


    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

    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 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 can be found, linked here.


    Downtown Redmond Link Extension (DRLE) - Sound Transit work

    East Lake Sammamish Trail South Segment B Stage 2 Construction

    This is a King County Trail Project

    The King County East Lake Sammamish Trail (ELST) South Segment B Phase 2 will begin construction in Spring 2022. All private property owners adjacent to the trail will be able to access their property during construction with limited exceptions for safety reasons.

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.
