S. Machias Rd and Dubuque Rd Intersection Improvement 


Snohomish County Public Works is planning to improve the intersection of South Machias Road and Dubuque Road.  The planned improvements to the S. Machias Rd /Dubuque Rd intersection are expected to reduce traffic delays during morning and evening peak hours, increase protection for Centennial Trail users crossing at Dubuque Rd, and improve traffic safety for left turn movements. 


This project is proposed for construction in spring 2026.


Funding has been secured through a $4.345 million Highway Safety Improvement Program (HSIP) grant.
