Larch Way/Logan Road and Locust Way Intersection Improvement Project

October 2023 Update

Drivers should expect single-lane closures periodically during the coming weeks along Larch Way, Locust Way and Logan Road. The closures allow Snohomish County PUD crews to prepare utility lines as part of the Snohomish County Public Works roundabout project at the Locust Way and Larch Way intersection. PUD crews will excavate trenches for the placement of conduits as part of the process of moving exiting utility lines underground. Trenching work will take place adjacent to and within the roadway on Larch Way, Locust Way, and Logan Road. In addition, crews will also be relocating overhead utility lines in preparation for construction. 

Construction of the roundabout is scheduled for summer 2024. 


Snohomish County Public Works is proposing to construct a single lane roundabout at the Larch Way/Logan Road and Locust Way intersection. In addition to the roundabout, roadway improvements consisting of curbs, gutters, and a shared-use path will be constructed. These improvements are expected to improve traffic flow and expand mobility for bicyclists and pedestrians. This project is currently in the design and right-of-way phase with construction estimated to begin in 2024.


  • 2018-2023: Design, survey, environmental review, right-of-way acquisition and public involvement
  • 2024: Construction


Funding for construction is secured using County Road Funds. More Information on the right-of-way acquisition process can be found on our Before we Build Pamphlet.
