Project FAQ

Q: What is the project purpose?

  • Currently, the two-lane stretch from OR 213 to Stafford Road carries over 100,000 vehicles daily, and drivers experience six and three-quarter hours of congestion daily. When completed, the project will reduce congestion and crashes, which improve safety, while also making travel times shorter and more predictable. Additionally, the work on the Abernethy Bridge will allow I-205 to remain open and passable following a major earthquake.

Q: What improvements are included in the project’s first phase starting this summer?

  • The first phase of the project will upgrade the Abernethy Bridge to withstand a major earthquake, improve interchanges at OR 43 and OR 99E, along with improving on- and off- to improve safety. A third travel lane in each direction will be added in the project area but the final lane configuration will be completed in a future phase.

Q: Why is it necessary to close the on-ramp from northbound OR 43 to northbound I-205?

  • Currently, there are two I-205 northbound on-ramps. One serves OR 43 northbound and the other serves OR 43 southbound. ODOT will remove the current I-205 northbound on-ramp from OR 43 and northbound traffic will instead use a roundabout to access northbound I-205. Consolidating these two separate northbound access points will eliminate the merging and weaving that currently occurs on I-205, reducing rear end crashes and improving traffic flow.

Q: Why are active transportation facilities not included on the Abernethy Bridge?

  • A bicycle/pedestrian facility is not included on the Abernethy bridge due to design and seismic capacity requirements, and because the bridge does not provide a connection to and from the locations people are trying to access by alternate mode. As an alternative, people walking or riding their bikes can use the Arch Bridge.

Q: How will traffic be impacted and managed during the first phase of construction?

  • Two lanes in each direction of I-205 will remain open during weekday business hours. Travelers can expect lane closures, directional and some full closures with signed detours at night or on weekends. Local roads will also experience lane closures and other traffic restrictions. Traveler information signs in the area, the project website, and TripCheck will inform drivers of construction impacts. The closures will likely begin in 2024.

Q: How is construction being funded? Will it be funded through I-205 tolling?

  • Toll revenue is needed to complete the I-205 Improvements Project and could be used to pay back funds borrowed for the Abernethy Bridge. More information about ODOT’s plans for tolling can be found on their website. This project is part of a regional Urban Mobility Strategy through ODOT’s Urban Mobility Office
