Indiana Eyes Toll Bonds and a P3 for $6.5 Billion I-70 Project

Why It Matters

If approved, Indiana’s waiver could set a national precedent, unlocking toll‑based financing for interstate upgrades and reshaping infrastructure funding models.

Key Takeaways

• Indiana seeks first federal toll waiver for an interstate
• $6.5 B I‑70 project financed half by toll-backed bonds
• Four bond issuances aim for $3.3 B net proceeds
• Debt‑service coverage projected above 3.0 times
• State open to public‑private partnership delivery models

Pulse Analysis

The federal government has long restricted tolling on the Interstate system, but Indiana’s waiver request under the Interstate System Reconstruction and Rehabilitation Pilot Program challenges that norm. By passing a state‑level tolling law and now seeking FHWA approval, Indiana aims to demonstrate that controlled toll rates and revenue retention can safely fund large‑scale projects without compromising the public good. This move reflects a broader shift toward flexible, user‑pay models as traditional gas‑tax revenues wane.

Financing the $6.5 billion I‑70 expansion hinges on a sophisticated bond strategy. Four staggered issuances beginning in 2028 are designed to generate $3.3 billion in net proceeds, while the toll authority projects a debt‑service coverage ratio above three, indicating strong cash‑flow resilience. Municipal bond investors are watching closely, as the structure offers a blend of public credit backing and dedicated toll revenue streams, potentially creating a new asset class for infrastructure funds. The absence of a TIFIA loan underscores Indiana’s confidence in market‑based financing and its desire to retain full control over toll pricing.

Beyond Indiana, the waiver could catalyze similar efforts in other states grappling with aging highways and constrained budgets. Public‑private partnerships are already on the table, offering risk‑sharing and operational expertise that could accelerate project timelines. If the FHWA grants the waiver, it may prompt a reevaluation of federal policy, encouraging a more permissive stance on tolling interstates and fostering innovative financing mechanisms across the nation’s transportation network.
