Public Works has proposed improvements to the intersection of Machias Cutoff and Williams Road south of Lake Stevens. Improvements include widening Machias Cutoff at this intersection to provide a westbound left turn pocket that will provide an additional lane for vehicles waiting to turn left onto Williams Road while allowing through traffic to continue. The road shoulders will also be widened to 5 feet at the intersection. Additionally, the proposed construction includes the removal of vegetation to enhance sight distance, new guardrails, street lights and stormwater treatment. The work will be done while minimizing impacts to critical areas near the intersection.

Visual: Proposed improvements.


Construction for this project is scheduled to begin in early spring 2017 and be completed by the end of 2017.


Funding for this project is provided by Snohomish County’s Road Fund.
