We’re celebrating the completion of all major elements of the OR 217 Auxiliary Lanes Project – delivered on time after four years of planned construction.
We worked to improve safety and address longstanding bottlenecks on OR 217 while also completing key connections in the adjacent bicycle and pedestrian network. We expect that the new improvements will decrease crashes on the highway by 20% to 30% and save over 73,000 hours of travel time every year.
Thank you to the community, our project partners, and construction crews for your patience and collaboration in achieving this important milestone.

The total project cost is $174 million primarily funded through the Keep Oregon Moving transportation package (House Bill 2017). The City of Beaverton and Washington County also contributed money toward the project.
Major project accomplishments:
- Placed over 19,000 tons of asphalt and added five miles of new auxiliary lanes, resulting in less congestion, increased merging distance and a safer highway with fewer crashes.
- Built a new southbound frontage road between Allen Boulevard and Denney Road. The new frontage road decreases highway merging, making trips safer for drivers.
- Rebuilt the Hall Boulevard overpass in Tigard including wider sidewalks and bicycle lanes, ADA-compliant sidewalk ramps and increased earthquake resilience.
- Widened the Hall Boulevard overpass in Beaverton by 19 feet to support a new sidewalk and bike lanes and fill in a missing link in the bicycle/pedestrian network. This work was in partnership with the City of Beaverton.
- Widened the sidewalk on the Denney Road overpass by 4.5 feet to accommodate two-way bicycle and pedestrian traffic.
The project also:
- Widened and reconfigured ramps at six interchanges.
- Connected the Fanno Creek Trail to Allen Boulevard, in partnership with the City of Beaverton, to complete the north/south parallel bicycle and pedestrian network.
- Added four sound walls.
- Widened shoulders to accommodate emergency response vehicles.
- Built nine retaining walls.
- Installed 2,100 feet of protective fencing and 23,000 feet of guardrail.
- Installed 19,000 feet of pipes and 18 storm swales and retention ponds.
What to expect as we finish final touches
Final touches and clean-up work will continue over the next several weeks. Final landscaping will continue into next spring as weather permits. You will continue to see some construction barrels, cones, and equipment in place as crews complete this finishing work.
No major traffic impacts are expected aside from short-term, intermittent single-lane and shoulder closures on the highway.
