Construction is expected to begin in late 2021 and continue through 2025.
The total project cost is $134 million. Highway safety improvements are primarily funded through the Keep Oregon Moving (House Bill 2017) transportation funding package passed by the Oregon Legislature.
Thanks to partnerships with the City of Beaverton and Washington County, this project will also include targeted improvements to local bicycle and pedestrian routes.

1 Southbound auxiliary lane from Beaverton-Hillsdale Highway to OR 99W.
2 Northbound auxiliary lanes from OR 99W to Scholls Ferry Road.
Replace the Allen Boulevard southbound on-ramp and the Denney Road southbound off-ramp with a frontage road to allow drivers to more safely travel south from Allen Boulevard to Denney Road.
Replace the Hall Boulevard overpass between OR 99W and Pfaffle Street, including new sidewalks and bike lanes.
Build sound walls at four locations to reduce noise for project neighbors.
Widen two ramps: the Denney Road southbound on-ramp and the OR 99W northbound off-ramp.
Auxiliary lanes will help make OR 217 safer and more reliable. They are ramp to ramp connections and 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. Studies show that auxiliary lanes reduce crashes by approximately 20%. Fewer crashes means a safer and more efficient highway.
For southbound travelers, a fully-connected auxiliary lane will run from Beaverton-Hillsdale Highway to OR 99W.
For northbound travelers, a new auxiliary lane will connect OR 99W to SW Greenburg Road. A second auxiliary lane will continue to SW Scholls Ferry Road.
The interchanges at SW Allen Boulevard and SW Denney Road are some of the worst bottleneck locations on OR 217. This is because the two interchanges are very closely spaced, leading to merging conflicts and crashes. The change we're making will reduce the amount of merging and in turn increase safety and reliability in the southbound direction.
We are replacing the SW Allen Boulevard southbound on-ramp and the SW Denney Road southbound off-ramp with a new southbound two-lane frontage road. The frontage road will work similarly to the one to the north connecting Canyon Road and Beaverton-Hillsdale Highway.
This change will permanently close the SW Allen Boulevard southbound on-ramp and the SW Denney Road southbound off-ramp and allow drivers to travel south more safely from SW Allen Boulevard to SW Denney Road, bypassing OR 217 entirely. It will also include a new bridge over Fanno Creek. Once it's complete, drivers should expect:
Two ramps will be widened to allow for more space for vehicles:
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 including:
We need to replace the SW Hall Boulevard overpass between OR 99W and SW Pfaffle Street to make room for the new auxiliary lanes on OR 217.
Building the new overpass as quickly as possible requires closing it to vehicles for up to six months. A temporary bike and pedestrian bridge will be available throughout construction, as well as a signed detour for those in cars. The new overpass will be earthquake resilient, American with Disabilities Act compliant, and have wider sidewalks and bike lanes. Exact timing for this work will be determined once construction starts.
We plan to make improvements to the SW Scholls Ferry Road, SW Allen Boulevard, and SW Denney Road overpasses:
Sound walls are barriers constructed between the highway and neighboring properties to reduce noise related to the highway. As part of the project, ODOT and acoustic engineers conducted a noise study to determine existing noise levels along OR 217 and what the noise levels will be after construction is complete. Results of the study showed that existing levels exceed the acceptable range in some locations and that there will be a small increase upon project completion. Based on this, sound walls were found to provide adequate benefits in four locations.
A majority of residents and property owners who would benefit from these sound walls voted in favor of each sound wall in 2019.
View the interactive map below to see the four sound wall locations and photo renderings of the sound walls.
Construction on different portions of the project will happen in phases over the course of four years. The sequencing and detailed schedule will be communicated as the project progresses through the phases.
We have been meeting with representatives from the construction industry to best plan for this upcoming multi-year construction project. Together, we are looking at construction sequencing and developing the best approach to minimize construction impacts and keep the work as efficient as possible.
In addition to nighttime lane and ramp closures and construction noise, anticipated traffic impacts over the life of the project include:
Detour routes will be established in partnership with the City of Beaverton, City of Tigard, City of Portland, Washington County and TriMet.
The addition of auxiliary lanes will be a benefit for freight and larger trucks by reducing merging and weaving around the various on- and off-ramps. This will smooth traffic flow, reduce the potential for crashes, and improve travel reliability for freight traveling through the area.
As part of our outreach efforts, we are talking with local businesses that rely on heavy freight about possible traffic impacts during construction and after completion of the project.
Stakeholders and ODOT are also working with the state's Mobility Advisory Committee (MAC) and will continue this discussion in early 2021 with a focus on anticipated closures for this project.
We want to make sure highway users and local residents are well informed. Our teams have and will continue to work to increase awareness of the project and keep channels open to learn about the communities’ needs. Past outreach activities have included in-person open houses, tabling at local events like the Tigard Farmer’s Market and Latino Festival, email updates, and direct mailers. If you live near one of the four sound wall locations, you may have also met one of our project team members on a canvassing route or informational events held during the voting period in 2019.
Top priorities from those we've heard from include making OR 217 more reliable and safer, protecting the wetlands around the highway, balancing the need to keep overpasses open while making safety and accessibility improvements, and making sure people know when to expect traffic impacts and construction noise.
We will continue to share information on these priorities and answer questions and comments through:
