Portland Bureau of Transportation outlines $1 billion Interstate Bridge Replacement project

The Portland City Council's Transportation & Infrastructure Committee meeting on August 11, 2025, highlighted significant developments regarding the Interstate Bridge Replacement (IBR) program, a major infrastructure project poised to reshape transportation in the region.

Key discussions centered on the project's scale, which includes five miles of interstate and seven interchanges, with an estimated cost of one billion dollars. The committee emphasized the importance of engaging with federally recognized tribes and the local community throughout the project's development and construction phases. This commitment to community involvement aims to ensure that the culturally rich area is respected and that residents have a voice in the process.

The IBR program is designed to accommodate various modes of transportation, including walking, biking, and public transit, reflecting a comprehensive approach to mobility. The project will be executed in manageable segments, with 28 different construction packages planned to facilitate local business participation and workforce development. The committee acknowledged the need for a robust workforce to meet the demands of this extensive project, indicating ongoing collaboration with labor and workforce development groups to create job opportunities.

In addition to the construction updates, the committee announced plans for a construction industry webinar in September to outline expectations and values associated with the project. They also anticipate releasing a cost estimate and financial plan update later this year, addressing inflation's impact on project funding.

As the IBR program moves forward, the committee reiterated its commitment to continuous community engagement, including participation in local events and providing resources for residents to stay informed. The anticipated amended record of decision is expected in spring 2026, paving the way for construction to begin.

This meeting underscored the city's dedication to not only improving infrastructure but also fostering economic growth and community involvement, ensuring that the IBR program aligns with the needs and aspirations of Portland residents.
