Officials overseeing the Interstate 5 bridge project between Portland and Vancouver announced a significant delay in releasing updated cost estimates. The new figures are now expected no sooner than spring 2026.
Coast Guard’s Decision Affects I-5 Bridge Cost Update
The U.S. Coast Guard’s upcoming decision on whether the bridge design should include a movable section is the primary reason for the delay. Such a design would likely increase the project’s cost by over $500 million.
As of December 2022, the estimated cost of replacing the bridge ranged from $5 billion to $7.5 billion. Since then, the situation has evolved. With rising costs of materials and labor impacting infrastructure projects nationwide, the new estimate could be significantly higher.
Construction Timeline and Design Features
Construction is anticipated to start in mid to late 2026. The envisioned bridge design includes:
- Three lanes in each direction
- One or two auxiliary lanes
- Shoulder space in both directions
- Light rail tracks
- Designated areas for cyclists and pedestrians
Moreover, the project entails upgrading intersections and traffic infrastructure in Portland, Hayden Island, and Vancouver. A new light rail station in Vancouver is also part of the initiative.
Funding and Ongoing Challenges
The project team has secured approximately $5.9 billion in funding. This includes:
- $217 million already allocated from Oregon and Washington
- $1 billion commitment from each state
- $2.1 billion in federal grants
- Up to $1.6 billion in future tolling revenue
Additionally, the team aims to secure a $1 billion federal grant for the light rail extension.
The Oregon law passed earlier this year, which removed tolling authorizations for certain projects, does not impact this initiative. However, lawmakers have expressed frustration over the ongoing delays in obtaining new cost estimates.
Future Prospects and Expectations
Carley Francis, the interim project administrator, emphasized the importance of transparent communication. She acknowledged the need for timely updates as the Coast Guard makes its decision, expected early next year.
Despite the setbacks, project leaders have not specifically indicated whether additional funding will be requested from either state soon. They stated more details would be available following the Coast Guard’s ruling on the bridge design.
Lawmakers from both Oregon and Washington remain vigilant, seeking clarity on the project’s financial outlook and timeline. The anticipation for a new cost estimate continues to rise as officials strive to keep stakeholders informed.
