S. Machias Road / Machias Cutoff Intersection Improvements

November 2019 Update

Installation of a new traffic signal is expected to take place in January 2020 at the S. Machias Rd/Machias Cutoff intersection and Centennial Trail crossing. Remaining work will be scheduled at that time.


To reduce delays and improve traffic operations, Public Works is planning improvements to the S. Machias Road and Machias Cutoff intersection in the Lake Stevens / Snohomish area. This project includes widening and realigning the roads leading up to the intersection, new signalization at the intersection, and the incorporation of Centennial Trail into a new crossing at the proposed signal. The project will also include new stormwater facilities. Construction for this project should be completed in February 2020.

This is one of many projects the departments of Public Works and Parks & Recreation are collaborating on. For more information on the Centennial Trail, visit the Parks & Recreation webpage.


  • 2016-2018: Design, survey, environmental review, right-of-way acquisition
    • The process of developing road projects takes several years. Many factors must be considered, including: location of homes; public right-of-way; stormwater runoff, drainage and water quality; wetlands and buffers; hilly terrain; sight distance; soils; traffic volumes; accident history; vehicle and pedestrian access; location of utilities; and information that residents provide about the area.
