Improving our economy by providing Oregonians safer, more reliable travel to access work and critical services, even after an earthquake or other major disaster. 

Site work underway! 

Tree removal is underway on each bank of the Willamette River underneath the Abernethy Bridge in Oregon City and West Linn to provide construction access for Phase 1A.

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 Comprehensive Congestion Management and Mobility Plan through ODOT’s Urban Mobility Office. 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 Phases and Funding

We are constructing the project in phases, with the first phase (Phase 1A) beginning in late spring/early summer of 2022.

Key Phase 1A 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.

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

  • Widening I-205 in the Phase 1A project area to allow a third travel lane in each direction. The final lane configuration will be completed in a future phase.

Tree removal will occur on each bank of the Willamette River underneath the Abernethy Bridge in Oregon City and West Linn to provide construction access for Phase 1A. This work will occur in October of 2021 to avoid nesting birds and heavy rain.

Project design and Phase 1A construction are fully funded. Phase 1A will use financing tools recently approved by the Oregon Legislature. Toll revenue is needed to complete future phases the I-205 Improvements Project, and will be used to pay back Phase 1A financing, pending a federal decision associated with the ongoing National Environmental Policy Act (NEPA) process. 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 »
