Project Overview

Improving Safety and Reliability

This project will address long-standing congestion on OR 217 between Beaverton-Hillsdale Highway and OR 99W due to too many closely spaced interchanges: 10 interchanges in just over seven miles! This is some of the shortest merging spacing in the region.

The interchange spacing, combined with 120,000 vehicles a day, leads to high crash rates and travel delays. This project will help everyone on OR 217 get where they need to go more safely and reliably.

We will construct auxiliary lanes in both directions of OR 217 as part of the improvements. Auxiliary lanes are ramp-to-ramp connections on the highway that help reduce congestion by giving drivers more space and time to merge safely. This decreases conflicts, improves safety and the flow of traffic, and ultimately allows the existing lanes to work more efficiently. We expect up to 73,000 hours of travel time saved each year with these improvements. Learn more about auxiliary lanes.

Along with improvements on the highway itself, project elements include building four sound walls, improving several overpasses, and adding stormwater management to protect Ash Creek, Red Creek, and Fanno Creek. Read more about bicycle and pedestrian improvements.

Project Benefits

The addition of new auxiliary lanes will reduce bottlenecks that cause congestion and crashes, which create delays for travelers and freight.
The new frontage road for southbound drivers connecting Allen Boulevard and Denney Road makes trips safer for drivers by decreasing the amount of merging on the highway.
New pedestrian and bicycle improvements enhance local neighborhoods and expand routes for people walking, bicycling and rolling.
