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.

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

The gas main replacement on NE 8th St is complete. Asphalt patching and some concrete work in this area is scheduled to start in early November. This work is dependent on weather conditions, as it requires dry surfaces. Work is anticipated to last for two weeks and will occur Monday through Friday, 9:30 a.m. to 3:30 p.m.

Gas main work in the Tree Farm Neighborhood is complete. Asphalt patching will take place once asphalt patching on NE 8th St is complete.

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.

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 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.
