S. Machias Road / Machias Cutoff Intersection Improvements

June 2019 Update

Construction Details:

  • Construction has begun and should be completed in November.
  • Crews will be working approximately Monday – Friday, 7 a.m. to 5 p.m.

Road & Trail Impacts

  • Throughout construction there will be single-lane closures on S. Machias Rd and Machias Cutoff during working hours.
  • Traffic will resume in both directions outside of work hours.
  • The Centennial Trail will remain open throughout construction with a short, paved detour.

Upcoming Closure

There will be a two-week full closure of Machias Cutoff at the intersection with S. Machias in mid-July. Signs near the intersection will announce the dates once they are determined. Work will extend through the weekends during the closure. The closure will not impact access to the Centennial Trail. Detour route is only for vehicles under 10,000 lbs.

January 2019 Update

From January to March 2019, utilities will be doing intermittent utility relocation. This will cause intermittent single-lane closures. 


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.

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.
