Next steps for the I-205 Toll Project environmental review process
In response to comments from agencies and community members on the 2023 Environmental Assessment, and because of the reduced I-205 Toll Project scope, we're preparing a Supplemental Environmental Assessment for release in 2024. The assessment will be based on a revised Project Description and revised Purpose and Need statement. The public will have another opportunity to provide input and comment on the Supplemental Environmental Assessment in 2024.
Stay informed on the analysis and public comment period by signing up for our newsletter.
Read on for information included in the 2023 Environmental Assessment, published in February 2023. A summary of comments and engagement to support this work is posted below:

This report identified the potential short- and long-term effects of the project on the transportation system, local communities, the economy, and the natural environment, and potential solutions to address negative effects. This process is required by the federal government, per the National Environmental Policy Act.
What did we study?The 2023 Environmental Assessment compared the effects in 2045 of two alternatives:
- Build Alternative, which includes building a third lane in each direction between Stafford Road and OR 43, a northbound auxiliary lane between OR 99E and OR 213, toll gantries and variable-rate pricing, and seismic bridge upgrades on I-205.
- No Build Alternative, which would have no additional improvements to I-205 and no tolls.

The 2023 Environmental Assessment compared short-term and long-term effects from both alternatives in several areas, including, but not limited to:
- Travel times, traffic volumes, and the extent of rerouting traffic from I-205 to local streets
- Safety for pedestrians, bicyclists, and vehicles
- Freight movement
- Local and regional economy
- Air quality, climate, and noise
- Social resources, communities, and environmental justice, including low-income households
- Natural and cultural resources
