Project Overview

This bottleneck is the last two-lane section of I-205 and drivers experience nearly seven hours of traffic backups and congestion each day.

We are addressing these issues with the I-205 Improvements Project, which is part of a regional Urban Mobility Strategy. The I-205 Improvements Project is intended to reduce congestion and crashes, while also making travel times shorter and more predictable. Project improvements will also allow I-205 to remain open and passable following a major earthquake.

Construction Impacts

The first phase of the project will primarily feature work under the existing bridge via barges in the Willamette River. However, the work at times will result in traffic impacts around the Abernethy Bridge. The Jon Storm parking lot under the bridge in Oregon City will close in June 2022 and will remain closed until upgrades are finished in 2025. Additionally, bridge construction will impact bike and pedestrian access along OR 99E. The project will result in full weekend, nighttime and directional closures. There will also be impacts to on-and off-ramps later in the construction process. Please visit the project website and to learn more about construction impacts.

Project Phases and Financing

Project design and the first phase of the project are fully funded. The remaining phases of the project are under evaluation. The first phase of the project will use financing tools recently approved by the Oregon Legislature. Toll revenue is needed to complete future phases the I-205 Improvements Project and could be used to pay back the funds borrowed for the Abernethy Bridge. The Toll Program is working to create a system that works for all travelers and local neighbors. To learn more about the I-205 Toll Project visit their website here »

First Phase Improvements Include:

  • Earthquake-ready improvements to the Abernethy Bridge.
  • Removing the current I-205 northbound on-ramp from OR 43 and replacing it with a roundabout.
  • Realigning or widening the on- and off-ramps at OR 99E.
  • Improvements for people who walk and bike on OR 43, Clackamette Drive and OR 99E.
  • Installing a sound wall near the southbound lanes of I-205 at exit 9.
  • Widening I-205 in the first phase of the project area will allow a third travel lane in each direction. The final lane configuration will be completed in a future phase.
