About

This project improves safety and mobility for all travelers by building a protected intersection. Curbed separation, shorter crossings and updated signal phasing and turn lanes reduce conflict points between travelers.

​What is a protected intersection?

This intersection style is a design approach to increase safety for pedestrians and people biking. It uses curb buffers to separate vehicles from pedestrians and​ people biking at key points within the intersection, reducing conflict points. 

This protected intersection is similar to other recent improvements in West Linn and is a part of the City of West Linn's OR 43 Concept Plan.
