Before PSE begins work they are required to have all underground utilities located. Residents should expect paint markings to appear, marking underground utilities, mid-April.

    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.

    Work on the gas main is expected to begin in early May and last for approximately three months. Work will take place Monday through Friday, 9 a.m. to 3 p.m. Drivers should expect delays and use caution. Impacted streets are NE 8th St, NE 7th Ct, 237th Pl NE, NE 6th Ct, NE 6th St, NE 4th Pl, 238th Ave NE and 239th Ave NE, Sammamish. See maps of work below for more details.


    Striping Maintenance Work

    The striping maintenance work was postponed due to unfavorable weather conditions. The City of Sammamish will perform the road striping maintenance work on West Beaver Lake Drive SE and East Beaver Lake Drive SE when weather conditions improve. This type of maintenance work requires dry road pavement. Fresh paint will be laid on top of the existing fog lines and center lines. The limit of work is shown in the map below.


    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.
