Project Details

OR 217 Auxiliary Lanes

Design Phase

Region 1: Portland metro and Hood River County (Beaverton, Tigard, Washington)

The Oregon Department of Transportation is working to improve the safety and reliability of OR 217 southbound from Beaverton Hillsdale Highway to Greenburg Road and OR 217 northbound from OR 99W to Scholls Ferry Road.  Construction is expected to begin in 2020.​  


Construction Impacts

During construction beginning in 2020, all existing lanes of OR 217 will remain open during weekday daytime hours.  Work that could impact travelers will be primarily performed during nights and weekends to minimize traffic impacts. People can expect traffic delays, noise and intermittent ramp closures.  While the Hall Boulevard bridge is replaced, half the bridge will remain open at a time allowing continued use for people driving, walking or bicycling.

Meetings and Events

Project design/engineering: 2017 – 2021
Construction expected: 2020 - 2022; OR 217 southbound improvements are constructed first, then the bridge replacement and OR 217 northbound



ODOT is in the design phase on a highway improvement project on OR 217.  Construction is slated to begin in 2020.  The main project elements are:

  • ​Build ramp-to-ramp auxiliary lanes on OR 217 southbound from Beaverton-Hillsdale Highway to Greenburg Road and build auxiliary lanes on OR 217 northbound from OR 99W to Scholls Ferry Road.  These will reduce recurring bottlenecks, provide a direct connection from one interchange ramp to the next and allow for more stable traffic flow at the OR 217 interchanges

  • Build a frontage road between the Allen Boulevard and Denney Road interchanges along OR 217 southbound.  This will eliminate the Allen Boulevard southbound on-ramp and the Denney Road southbound off-ramp.  Instead, drivers will use the new frontage road to travel between the two interchanges.  These interchanges are one of the worst bottleneck locations on OR 217 and also one of the most dangerous.  A frontage road will reduce the weaving movements and and crashes.  The newly configured Allen/Denney interchange will function similarly to the Canyon Road/Beaverton-Hillsdale Highway interchange to the north

  • Build several retaining walls

  • Replace one of the Hall Boulevard bridges over OR 217.  There are two Hall Boulevard bridges over OR 217 - one near Washington Square and one farther south at SW Pfaffle Street.  The bridge being replaced is the one farther south, at SW Pfaffle Street (near OR 99W in Tigard).  The bridge replacement is needed to accommodate the new auxiliary lanes

  • Conduct a noise study to evaluate the feasibility of building sound walls.  The final outcome of the noise study is not yet known
Why is this project needed?
OR 217 connects I-5 and U.S. 26, two major transportation corridors in the Portland metro area.  This seven-mile stretch of highway carries up to 120,000 vehicles a day. The highway has 10 interchanges in just over seven miles of highway, with some of the shortest interchange spacing in the region.  Short weaving distances contribute to high crash rates, with approximately 70% of crashes as rear end collisions. Afternoon peak travel times on OR 217 are unpredictable and unreliable, varying from less than 10 minutes to more than 30 minutes. Closely spaced interchanges cause significant bottlenecks, leading to high crash rates.  Crashes increase congestion, causing more delays.

ODOT is focusing on lower-cost, effective and immediate solutions to improve bottleneck locations.  One solution is building auxiliary lanes.

Auxiliary lanes provide a direct connection from one interchange ramp to the next, by separating on- and off-ramp merging traffic from through traffic.  By separating slower traffic, it in turn smooths traffic flow, reduces the potential for crashes and improves reliability.

These improvements are not intended to address capacity-related congestion, but rather to provide immediate and long-term safety improvements at bottleneck locations.

Cost and Funding

The Oregon Legislature allocated $98 million toward this project in House Bill 2017. With the passage of HB 2017, also called Keep Oregon Moving, the Oregon Legislature made a significant investment in transportation to help further the things that Oregonians value—a vibrant economy with good jobs, strong communities with a good quality of life, a clean environment, and safe, healthy people.  Read more about HB 2017.​

Local and regional traffic on OR 217 will benefit most from the auxiliary lane extension.  Only 10% to 15% of the trips on OR 217 go from one end to the other.  The other 85% to 90% of trips use one or more of the interchanges along OR 217.  The auxiliary lanes will separate slower traffic movements from the freeway, helping smooth traffic flow, reduce the potential for crashes and improve traffic reliability.  This will allow drivers to do less weaving and have more time to make lane changes.  Overall, this will improve the regional economy by facilitating the movement of goods and services.

Additionally, the new frontage road at the Allen Boulevard and Denney Road interchanges will remove the extremely short weaving section that is one of the worst bottlenecks on OR 217 and has a high frequency of crashes.  This road will also provide a place for existing traffic to wait to access cross streets, rather than backing up onto the highway.
