Eight Reasons the Interstate Bridge Project Shouldn’t–And Can’t Legally–Move Forward

Key Takeaways

• FEIS covers $15.5 bn, but agencies plan only $7.6 bn core.
• Project lacks fiscal constraint; DOTs cannot guarantee funding.
• Truncated design fails “independent utility” test, violating federal law.
• Traffic forecasts overstate demand; actual I‑5 volumes have fallen.
• Benefit‑cost ratio now negative, breaching DOT grant requirements.

Pulse Analysis

The Interstate Bridge Replacement (IBR) has become a textbook case of how oversized infrastructure planning can clash with federal regulations. The newly released Final Environmental Impact Statement (FEIS) outlines a $15.5 billion corridor that includes extensive highway widening and a light‑rail component. However, both ODOT and WSDOT have signaled they will only fund a $7.6 billion "core" segment, stripping away the transit elements that justified the original environmental analysis. This mismatch invalidates the FEIS under the National Environmental Policy Act because the agency cannot demonstrate that the proposed construction will deliver the projected environmental benefits.

Beyond procedural flaws, the IBR project is financially untenable. Federal law mandates that any federally‑assisted project be part of a fiscally constrained plan, meaning the agency must show reliable funding sources for the entire lifecycle. Oregon and Washington transportation departments are effectively broke, with no guaranteed revenue streams to cover the $15 billion price tag. The truncated core still lacks "independent utility," creating a bottleneck that would not function without additional, unfunded improvements. This violates DOT regulations that prohibit half‑built projects and jeopardizes the eligibility for federal grants.

The broader implications extend to climate policy and taxpayer stewardship. The FEIS projects a 25 percent rise in vehicle miles traveled, directly contradicting Oregon’s legally mandated 10 percent reduction in driving. Moreover, the benefit‑cost analysis now shows benefits of roughly $4 billion against costs exceeding $15 billion, breaching the cost‑effectiveness threshold required for federal aid. Coupled with half‑a‑billion dollars already spent on consulting, the IBR exemplifies a "forever project" that drains public resources without delivering measurable public value. Stakeholders must reassess the plan, align it with fiscal realities, and explore more sustainable, cost‑effective alternatives.
