About the Project

The I-5 Rose Quarter Improvement Project will make travel more predictable and safer for people driving and transporting goods on I-5 between I-84 and I-405 by adding auxiliary lanes and shoulders that smooth traffic flow. The project includes a highway cover to reconnect the Albina neighborhood and street improvements that will enhance safety and access for people walking, rolling, biking, riding transit and driving on local streets. The project will support the regional economy, future economic development and a more connected Albina community.

Project Purpose:

  • The purpose of the Project is to improve the safety and operations on I-5 between Interstate 405 (I-405) and Interstate 84 (I-84), at the interchange of I-5 and N Broadway and NE Weidler Street (Broadway/Weidler interchange), and on adjacent surface streets in the vicinity of the Broadway/Weidler interchange.

In Support of This Purpose, The Project Would Also:

  • Support improved local connectivity and multimodal access in the project area and between neighborhoods east and west of I-5.
  • Complement the land use, urban design and transportation system envisioned for the planning districts of Lower Albina and Lloyd as articulated in the City of Portland’s adopted plans.

Project Need:

I-5 between I-84 and I-405 is the top traffic bottleneck in Oregon, and the 28th worst freight bottleneck in the nation. The project is needed to address the following:

  • I-5 Safety
  • I-5 Operations & Reliability
  • Broadway/Weidler Interchange Operations
  • Travel Reliability

Project History

The I-5 Rose Quarter Improvement Project has been part of regional transportation conversations since the 1980s. Learn more:

Project History

Key Project Features Include:


Highway Cover

A new cover over I-5, similar to a very wide bridge, that reconnects local streets and creates new community spaces on top for future development and economic opportunities.


Hancock Crossing

A new east-west roadway crossing over I-5 that reconnects Hancock Street across the highway, adding another crossing north of Broadway and Weidler.


Multimodal Local Street Improvements

A variety of street improvements for people walking, biking and rolling.


Green Loop Connection

A link on Broadway and Weidler to the city’s Green Loop, a 6-mile bike and pedestrian path that allows people to travel safely through the heart of the city.


Auxiliary Lanes and Shoulders

Ramp-to-ramp connections, paired with wider shoulders, that improve safety and reduce congestion at the state’s top bottleneck.


I-5 Southbound Off-ramp Relocation

Relocation of the I-5 southbound off-ramp from Vancouver/Broadway to the south, connecting with N Wheeler Avenue.

Supplemental EA

The Supplemental Environmental Assessment (EA) was published on November 15, 2022, starting the 50-day comment period. The document updates the information presented in the 2019 EA and the 2020 Revised EA based on changes to the design of the highway cover. The Supplemental EA describes why the project is proposed, what changes have been made to the design, and how the project would benefit and impact the social, economic and physical environments.

Review the information below and submit comments through midnight on January 4, 2023.

National Environmental Policy Act

The project is following the requirements of the National Environmental Policy Act (NEPA), which is a federal law requiring agencies seeking federal funding or approval to assess the potential impacts of their project on the natural, human and built environments. NEPA environmental documents compare the effects of building a project with the effects of not building a project.

In 2019, ODOT and the Federal Highway Administration (FHWA) prepared an EA for the project, followed by a public comment period in accordance with NEPA. In 2020, ODOT and FHWA prepared a Revised EA that responded to public and agency comments on the 2019 EA, and FHWA signed a Finding of No Significant Impact (FONSI) for the project. In 2021, ODOT made design changes at the direction of the Oregon Transportation Commission based on an Independent Cover Assessment and community feedback. The FHWA determined that the design changes warranted additional review in accordance with NEPA, and rescinded the 2020 FONSI. As a result, ODOT incorporated the design changes into a Revised Build Alternative, and with FHWA, prepared the Supplemental EA to evaluate the benefits and impacts of the Revised Build Alternative compared to a No-Build Alternative.

The Design Changes

  • Provide one larger and continuous highway cover that could support buildings up to three stories tall, and possibly up to six stories tall. The prior design featured two smaller covers that could not support buildings.
  • Maintain the N Flint Avenue connection and reconnect N Hancock Street to NE Hancock Street over I-5. The prior design removed the N Flint Avenue connection over I-5.
  • Relocate the I-5 southbound off-ramp at NE Broadway farther south to NE Wheeler Avenue near the Moda Center. The prior design maintained the I-5 southbound off-ramp in its existing location at the intersection of NE Broadway.
  • Connect the City of Portland’s Green Loop for pedestrians and cyclists on Broadway and Weidler Streets. The prior design included a separated bicycle and pedestrian bridge referred to as the Clackamas bicycle and pedestrian bridge.

Community Involvement

Community engagement is central to the project. ODOT recognizes past harms to members of the historic Albina community and is committed to a transparent and inclusive decision-making process. The project serves as an opportunity to elevate the voices of the Black community and bring their vision to the quarter.

Public input informed the current design through community briefings, design workshops, online open houses and advisory committee meetings. Comments received during this Supplemental EA comment period will be considered by the project team and the Federal Highway Administration.  

Elevating Community Voices Through:

Project Values

By centering restorative justice as one of the project’s primary values, ODOT is doing business differently by facilitating community involvement through informed project design and workforce opportunities for the Black community.

Advisory Committees

Two advisory committees oversee and provide direction for the project. All committee meetings are open to the public and welcome public comment.

  • The Historic Albina Advisory Board (HAAB) elevates the voices in the Black community and ensures that the project outcomes reflect community interests and values.
  • The Community Oversight Advisory Committee (COAC) works to ensure the construction contractor meets its workforce and project contracting goals with Disadvantaged Business Enterprises.

Online Design Surveys

We’re hosting a series of online design surveys to collect community feedback on designs that honor the historic Albina community and could be added to highly visible areas of the project infrastructure.

Collaborative Contracting

We’re reshaping the way we do business by taking a more collaborative approach to contracting work for the project and encouraging the participation of Disadvantaged Business Enterprises.

Other Ongoing Community Engagement Efforts Both Online and In-Person:

  • Engagement with youth and students of color.
  • Participation and sponsorships at community events.
  • Incentivized engagement with community-based organizations.
  • Open houses, public workshops and forums.
  • Direct outreach to the faith community, local businesses, community leaders and elected officials.

How to Comment

Information is available in alternative formats upon request.

  • You can help us respond to questions and concerns by being as specific as possible with your comments. This means including page numbers or citing specific parts of the EA document in your comment. Additional explanations, facts and references are also helpful, when appropriate. Specific interests, thoughts and concerns are more effective than broad statements and more likely to be used to improve the final documents and analyses.
  • As a reminder, commenting on the Supplemental EA is not a vote on the project but an opportunity to provide decision-makers your input about the environmental analysis of the preferred design alternative.

There are several ways to submit a comment, and all comments received through these channels are viewed equally:
