Road Projects for the Week of October 1 - 7
SE 24th Street Electric System Upgrade Project
This is a PSE project. PSE and Potelco electric crews will be installing a new recloser on an existing utility pole on SE 24th Street between 244th Ave SE and 245th Ave SE. The work began on Wednesday September 28th and will complete on approximately Friday September 30th. SE 24th Street will be reduced to one lane with flaggers and signs directing traffic safely around the work area.
Sidewalk Curb Ramp Reconstruction
The City of Sammamish is working to implement its ADA Transition Plan. Sidewalk ramps in high pedestrian use areas and on streets scheduled for resurfacing next year are being reconstructed to improve accessibility. Below is more information on specific locations.
The hours of work are 7:00 a.m. - 3:00 p.m. Due to the nature of this work, the sidewalks along the area of work will be closed and pedestrian detour routes will be provided and indicated with signage. During certain portions of this work, the road will be reduced to one lane of traffic. Reader boards are posted around areas of work to alert drivers and pedestrians. Pedestrians should expect delays and plan their routes accordingly. Drivers should use caution and expect minor delays.
228th Avenue SE from Issaquah Pine Lake Road SE to SE 24th Street
Work in this location will occur between August and October. The work crew will be staggering work at intersections to keep pedestrian pathways open.
The specific areas of work are as follows:
- Eastbound SE 24th St, concluding at Audubon Park Dr SE
- The entrance to Discovery Elementary School
- The intersection of 228th Ave SE and SE 24th St
- Southbound 228th Ave SE along Pine Lake Park

Work on these streets is scheduled to last through December. The work crew will be staggering the construction to minimize impacts to pedestrian routes. Below is a map with the specific areas of work indicated in green
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.

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.
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 began in October. Work on NE 8th St. will take place Monday through Friday, 9:30 a.m. to 3:30 p.m.
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.
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 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
New School Zone Flashers on Issaquah - Pine Lake Road
The city has installed three new school zone flashing signs on Issaquah-Pine Lake Road near Cedar Trails Elementary to alert drivers of walking students and the reduced speed of 20mph during drop off and pick up times. The exhibit below shows their locations. Drivers should slow down and use caution when these signs are flashing in the mornings and afternoons.
Changes to SE 32nd and 244th Ave SE Intersection
The city changed the intersection of SE 32nd and 244th Ave SE into an all-way stop control due to traffic concurrency issues. New stop signs and stop bars were placed on the approach legs of SE 32nd, in addition to the existing stop sign on 244th. This change took place the week of August 15th and advance warning message signs are in place. Drivers should slow down use caution with this new traffic control change.
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.
Downtown Redmond Link Extension (DRLE) - Sound Transit work
This is a City of Redmond and Sound Transit project.
Crews are scheduled to close the on-ramp from Redmond Way to westbound SR 520 for four months in order to build a new on-ramp. This is part of the Redmond Link Extension construction. Drivers should plan accordingly due to the ramp closure. To stay up-to-date and learn more about this project, please visit the DRLE tab in Cone Zone.
