84th St NE and 123rd Ave NE Intersection Improvements

To improve traffic flow and reduce the risk of collisions, Snohomish County Public Works is making intersection improvements at 84th St NE and 123rd Ave NE. The two-lane 84th St NE serves as a main connection for drivers traveling between Marysville and Granite Falls. Traffic on 123rd Ave NE is currently controlled by a two-way stop. The county proposes to construct a roundabout at this intersection to improve traffic flow and safety.


This project is proposed for construction in spring 2026.
