The Interstate Bridge replacement project, connecting Portland and Vancouver on I-5, is moving forward. Construction is expected to begin after federal approval and a final environmental impact statement are secured in 2026. This update follows recent discussions by a bi-legislative committee overseeing the initiative. The project's next phase involves a crucial decision on bridge type by the United States Coast Guard (USCG).
Meanwhile, thousands of Vaux swifts are preparing for their annual fall migration to Portland. These small birds typically roost in the chimney of Chapman Elementary School, drawing many observers. Last year, a significant shift in their roosting patterns was observed, prompting increased monitoring efforts by the Bird Alliance of Oregon.
Key Takeaways
- Interstate Bridge replacement project aims for 2026 federal approval.
- USCG decision on bridge type (fixed vs. movable span) is pending.
- Vancouver Mayor warns of $1 million daily cost for delays.
- Vaux swifts are expected in Portland for fall migration.
- Bird Alliance of Oregon is monitoring swift roosting sites after last year's shift.
Interstate Bridge Project Nears Key Federal Approvals
The Interstate Bridge replacement coordinator, Greg Johnson, confirmed that the project is on track to obtain necessary federal approvals. The team anticipates receiving a finalized environmental impact statement by 2026. This milestone is essential before construction can begin on the vital I-5 connection.
A significant next step involves an application to the United States Coast Guard (USCG). This application will determine the required bridge type. Johnson stated,
"That will tell us whether they will allow us to build a fixed span at 116 feet or we will be required to build another moveable span. We're moving both of those options forward."
The choice between a fixed or movable span could have substantial implications. A movable span might affect both the construction timeline and the overall cost of the project. Project officials are evaluating these factors carefully.
Project Scope
The Interstate Bridge replacement project is a major infrastructure initiative. It aims to replace the existing Interstate Bridge, which is over 100 years old. The new bridge will improve traffic flow and safety on Interstate 5 between Portland, Oregon, and Vancouver, Washington.
Concerns Over Potential Delays and Costs
Vancouver Mayor Anne McEnery-Ogle has repeatedly voiced concerns about possible delays. She highlighted that any postponement in the project's timeline could result in significant financial penalties. According to Mayor McEnery-Ogle, each day of delay could cost approximately $1 million.
Mayor McEnery-Ogle also pointed to a critical deadline related to environmental protection. She warned that a stall in the process could cause the project to miss the 2027 "in-water work window." This window is crucial for construction activities that occur in the river. Missing it would lead to an additional full year of delay. This is due to regulations designed to protect salmon migration patterns in the waterway.
Background on Bridge Tolls
The new Interstate Bridge is expected to include tolls. An expert previously warned that these tolls on Interstate 5 could reach $20 for some crossings. This potential cost is a factor for commuters and local businesses, and it remains part of the broader discussion surrounding the project's financing.
Vaux Swifts Return to Portland: Monitoring Migration Patterns
As September approaches, thousands of Vaux swifts are preparing for their annual migration. These small birds are known to gather at Chapman Elementary School in Portland. For over three decades, the school's chimney has served as a temporary nightly roost for these swifts during their fall journey.
The spectacle of thousands of birds funneling into the chimney at dusk attracts hundreds of visitors each year. Onlookers gather to watch the swifts fly in formation before entering their roost. This unique event has become a local tradition.
Changes in Roosting Behavior Observed
Last year, the number of swifts roosting at Chapman Elementary School dropped significantly. This change was noted by the Bird Alliance of Oregon. The reason for this shift remains unclear to researchers. While numbers decreased at Chapman, roosting activity at other chimneys on Portland's east side increased substantially.
Joe Liebezeit, the Statewide Conservation Director for the Bird Alliance of Oregon, commented on these observations.
“Last year, we did see that the birds that were roosting at Chapman went to other chimneys scattered around. We noticed that when those numbers [at Chapman] dropped off, they rose at other sites – so we think they were moving, and we may see that again,”Liebezeit explained.

- Recent Trend: Decreased numbers at Chapman, increased at other east side chimneys
- Monitoring: Volunteers preparing to observe multiple locations
Community Involvement in Swift Monitoring
The Bird Alliance of Oregon is preparing its team of volunteers to monitor several locations across the city this season. This effort aims to track the swifts' movements and understand their updated roosting preferences. The alliance encourages public participation in this conservation effort.
If members of the public notice a chimney with hundreds of birds roosting this season, they are asked to report it to the Bird Alliance of Oregon. The organization maintains a dedicated web page for the swifts. This page provides more information about the migration and details on how individuals can contribute to their monitoring and conservation efforts.
Vaux Swift Facts
Vaux swifts are small, migratory birds found in western North America. They are known for their rapid, erratic flight. During migration, they often gather in large flocks and use hollow trees or chimneys as communal roosting sites.
