PORTLAND, Ore. — Members of the Portland Design Commission met Thursday to review early design concepts for the long-awaited Interstate Bridge replacement, weighing how the project will connect communities, support multiple modes of travel, and reflect the character of both Oregon and Washington.
Concerns Over Vancouver Connection
Commission Chair Brian McCarter focused on how the new bridge would link to the Vancouver Waterfront on the north end. Current plans call for a shared-use ramp for pedestrians and cyclists, but McCarter worried that the long, winding path may discourage use.
“I’m having a struggle with the configuration being this long,” McCarter said. “Is this the only way to do this, or could this be enhanced by some stairs, some elevators at strategic locations?”

Integrating Transit and Active Transportation
Brenda Martin, major projects and transit manager for the Portland Bureau of Transportation, emphasized the need for better integration between the bridge’s light rail line and the adjacent bicycle and pedestrian path. She argued that with transit and active transportation in such close proximity, planners should ensure seamless connections to maximize accessibility.
Cohesive Yet Distinct Designs
Another area of debate centered on whether the bridge landings should look the same on both sides of the river. Commissioner Zari Santner argued for variety, suggesting that the Oregon and Washington ends could incorporate different design details that reflect local context.
McCarter agreed but stressed that differences must fit within a broader design vision. “Variety is great as long as it’s within an overall story,” he said.
Transparency and Views
McCarter also pushed for transparent bridge railings, so pedestrians and cyclists can enjoy unobstructed views of the river and surrounding landscape. He argued that opening up sightlines would make the bridge not only functional but also a more pleasant public space.
Next Steps in Review
The commission is expected to vote on Sept. 18 on whether to approve a formal letter of recommendations to the Interstate Bridge Replacement Program. The letter would reflect the commission’s early priorities for shaping design as the project advances.
A Massive Undertaking
Replacing the Interstate Bridge will be one of the most ambitious infrastructure projects in the Pacific Northwest in decades. Construction is expected to span 15 years and be divided into 24 separate construction packages.
The project was estimated in 2023 to cost between $5 billion and $7.5 billion, though officials say updated figures due later this year or early 2026 will likely be higher.
Balancing Vision and Cost
With billions at stake and decades of community impact ahead, commissioners stressed the importance of striking a balance between functionality, cost efficiency, and design quality. The decisions made in these early design stages, they noted, will shape the daily experience of thousands of commuters, cyclists, and pedestrians for generations to come.
