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 End Point: Approximately 750’ south of the intersection of NE 16^thStreet / 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.
