East Lake Sammamish Trail South Segment B Stage 2 Construction

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 16^th 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.

Puget Sound Energy Natural Gas Project

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. Residents of the Tree Farm Neighborhood should expect emails and/or door hanger notices about this work.

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. The bus stop on NE 8th St will be moved 250 ft. west of its current location. Some street parking will be impacted. “No parking” signs will be placed in the areas prior to work beginning.

Work on the gas main is expected to begin tentatively on May 16, 2022, and last for approximately three months. Work will take place Monday through Friday, 9:30 a.m. to 3:30 p.m. on NE 8th St. Work hours at the other locations may vary. Drivers should expect delays and use caution.

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 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.

Roundabout at ELSP and SE 43rd Street Revisions
