This information reflects the most recent data available at the start of project design. In spring 2020 we saw a decrease in traffic volumes on I-205 due to Covid-19 and traffic volumes have been steadily rising since.
We are in the final steps of awarding a construction contract to Kiewit Infrastructure West for work on the Abernethy Bridge widening. Work is expected to start in June!
The Jon Storm parking lot under the bridge in Oregon City will close starting May 31, 2022 and will remain closed until upgrades are finished in 2025
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.
This information reflects the most recent data available at the start of project design. In spring 2020 we saw a decrease in traffic volumes on I-205 due to Covid-19 and traffic volumes have been steadily rising since.
The project reduces crashes and daily congestion by 4.75 hours each day by adding a third lane in each direction with shoulders that could accommodate future transit opportunities.
Improved interchanges and on- and off-ramps will make travel safer, resulting in fewer crashes.
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.
We are constructing the project in phases, with the first phase beginning in summer of 2022.

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 »
