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 began 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 8thStreet / East Lake Sammamish Parkway SE (STA 371+59)
  • Project End Point: Approximately 750’ south of the intersection of NE 16thStreet / 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.

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.
