The OR 217 Auxiliary Lanes project aims to improve safety and relieve long-standing traffic bottlenecks between Beaverton-Hillsdale Highway and OR 99W. The highway has 10 interchanges in just over seven miles and has some of the shortest merging spaces in the region.
Oregon Department of Transportation will add auxiliary lanes, or ramp-to-ramp connections, to help reduce bottlenecks by giving drivers more space and time to merge safely.
In partnership with the city, the project will extend the Fanno Creek Trail along the east side of the highway to Allen Boulevard, thereby completing the parallel bike path network from OR 99W to Southwest Allen Boulevard. Additional bike/pedestrian improvements are planned on several overpasses in the project area.
The Southwest Allen Boulevard and Southwest Denney Road area will also see the construction of a new southbound frontage road replacing the closely spaced Allen on-ramp and Denney off-ramp. Construction of four sound walls is also planned.
Construction is set to begin in late 2021 and continue through 2025. ODOT will coordinate detour routes during construction with the cities of Beaverton, Tigard and other local agencies.
