Opportunities in U.S. Infrastructure: Funding the Massive Capital Gap

In this Informed Infrastructure Change Leader column, Bob Hellman lays out the sheer scale of America's infrastructure funding gap and argues that private capital is increasingly the only realistic way to close it. He opens with the recent federal infrastructure bill and the collapse of Baltimore's Francis Scott Key Bridge, using them to argue that even a large federal downpayment makes only a small dent in the impending safety and logistics crisis facing the country. Trillions in repairs and upgrades are needed while governments at every level are, in his words, gasping for financial resources.

The United States, he argues, never built its infrastructure with long-term maintenance in mind. The federal government financed the construction of the Interstate Highway System but failed to establish a mechanism to maintain it, and the Highway Trust Fund, which offers some money toward repairs, has repeatedly run dry and proven insufficient for the scale of the need. Where other countries developed sinking funds to maintain roads, bridges, schools, utilities, and other assets, the United States largely lacks any cohesive funding effort, in part because Americans have come to perceive their use of infrastructure as essentially free. That perception, he writes, leaves a critical driver of the economy chronically underfunded and allowed to decay.

He then quantifies the crisis. Of more than 600,000 U.S. bridges, roughly a fifth need significant repair, and with per-bridge repair costs averaging $1.5 million to $10 million or more, fixing them all would run into the billions. Yet the latest infrastructure bill, he notes, allocates less than $100 million per state per year for bridge repairs over five years, a meaningful sum but far short of the problem. Bridges are only part of it. Roads, port facilities, school buildings, electric grids, and water systems face similar disrepair, and bringing all U.S. school buildings up to modern building codes alone is estimated at around $568 billion.

Hellman's resolution is that governments need capital infusions they cannot supply on their own, and that private infrastructure investment has been stepping in to fill the void. Private capital, he argues, lets governments cover the cost of repairing or replacing infrastructure while freeing their own scarce resources for other community needs, much as private equity takes an ownership stake in a business. He positions private investment not as a last resort but as the most viable, scalable option for states and localities to address urgent needs rapidly without burying their governmental units in new debt.
