i-205 Abernethy Bridge Aerial

Project Overview

Over 100,000 vehicles a day use the seven-mile stretch of I-205 from Stafford Road to OR 213 in Oregon City. 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.

Project Benefits

Stopwatch Icon

Reduced Congestion & Travel Times

Additional travel lane in each direction will make travel faster and more predictable.

Cars Crashing Icon

Fewer Crashes

Improved interchanges and on- and off-ramps will make travel safer, resulting in fewer crashes.

Seismic Ready Icon

Earthquake-Ready Bridges

The Abernethy Bridge and eight other I-205 bridges will be upgraded or replaced to withstand a major earthquake. An earthquake-ready corridor will support this critical lifeline route in providing supplies and services to the region after a disaster.

First Phase Improvements:

  • 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.

  • Sound wall near the southbound lanes of I-205 at exit 9.

  • Widening I-205 in the first phase of the project area to allow a third travel lane in each direction. The final lane configuration will be completed in a future phase.

Project design and the first phase of the project are fully funded. Phase 1 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. Get involved and learn more about the I-205 Toll Project »
