Improving Safety and Travel Reliability
The OR 217 Auxiliary Lanes Project will address long-standing bottlenecks on the highway between Beaverton-Hillsdale Highway and OR 99W due to too many closely spaced interchanges. Auxiliary lanes are ramp-to-ramp connections that help reduce bottlenecks 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 will also address one of the worst bottleneck locations at the Allen Boulevard and Denney Road interchanges by adding a new frontage road, replace a major bridge structure and build four sound walls.
We aren't just making improvements to the highway itself. We also need to make the area surrounding OR 217 safer for all users. In partnership with the City of Beaverton and Washington County, we are making targeted improvements to local bicycle and pedestrian routes.
OR 217 between Beaverton and Tigard has 10 interchanges in just over seven miles and 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. The interchanges at Allen Boulevard and Denney Road are some of the worst bottleneck locations. This project will help minimize bottlenecks and help everyone on OR 217 get where they need to go.
Major elements of the OR 217 Auxiliary Lanes Project include:
- Add southbound auxiliary lane from Beaverton-Hillsdale Highway to OR 99W.
- Add northbound auxiliary lanes from OR 99W to Scholls Ferry Rd.
- Replace the Allen Boulevard southbound on-ramp and the Denney Road southbound off-ramp with a new frontage road. This will reduce the amount of merging on the highway and in turn increase safety and reliability.
- Replace the Hall Boulevard overpass between OR 99W and Pfaffle Street, including wider sidewalks and bike lanes.
- Build four sound walls to reduce noise for project neighbors.
- Widen two ramps: the Denney Road southbound on-ramp and the OR 99W northbound off-ramp.
What is an auxiliary lane and how will they improve travel on OR 217?
Auxiliary lanes are ramp-to-ramp connections that help reduce bottlenecks by giving drivers more space and time to merge safely.
Studies show that auxiliary lanes reduce crashes by approximately 20%. Fewer crashes mean a safer and more efficient highway.
Pedestrian and Bicycle Improvements
This project also includes targeted improvements to local bicycle and pedestrian routes, in partnership with City of Beaverton and Washington County, including:
- Extend Fanno Creek Trail along the east side of OR 217 up to Allen Boulevard. This connection completes the OR 217 parallel bike path network from OR 99W to Allen Boulevard.
- Widen sidewalk on north side of Denney Road from Fanno Creek Trail to SW 105th Avenue.
- Build sidewalks and bike lanes on Hall Boulevard from Cascade Avenue to Scholls Ferry Road.
ODOT's noise study found that sound walls could help reduce highway noise for project neighbors along four section of OR 217. A majority of residents and property owners who would benefit from these sound walls voted in favor of each sound wall in 2019. Read more about the process on the sound wall page.
We will keep you informed
ODOT is committed to keeping you informed during construction. We will share progress and respond to questions with tools including:
OR 217 southbound Beaverton-Hillsdale Highway to OR 99W and OR 217 northbound OR 99W to Scholls Ferry Road
Cost and Funding
The total project cost is $134 million. We are delivering on a legislative commitment to make these safety improvements through
the Keep Oregon Moving (HB 2017) transportation funding package. Read more about HB 2017.
Project benefits include:
- The addition of new auxiliary lanes help prevent bottlenecks that cause congestion and crashes, which create delays for travelers and freight.
- A new frontage road for southbound drivers connecting Allen Boulevard and Denney Road will make 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 pedestrians and people on bikes.
