180th St SE and Interurban Blvd Intersection Improvement (2013)


Completed 2013

Snohomish County designed this project to address several traffic and ciruclation issues along 180th Street SE in the area of Interurban Boulevard. Two adjacent branches of Interurban Boulevard intersected the north side of 180th Street SE a short 125 feet from each other. The existence of the two roadways in close proximity was not the optimum configuration for accessing 180th Street SE (view map (PDF)).

A new section of 59th Avenue SE was constructed north of 180th Street SE and W. Interurban Boulevard was terminated in a cul-de-sac north of 180th Street.

The new intersection of 59th Avenue SE at 180th Street SE eliminates the older, skewed angle approach of W. Interurban Boulevard at 180th Street SE and improves intersection recognition for East and West bound traffic on 180th Street SE. The new intersection also improves the sight distance for drivers entering 180th Street SE.
