2025: The $2.5 Trillion Backlog

America built the world's greatest road network. Now we can't afford to maintain it—and the bill is coming due.

```

1. The Numbers That Should Terrify You

In 2025, the American Society of Civil Engineers released their latest Infrastructure Report Card. The Interstate Highway System—once the crown jewel of American engineering—received a grade of C-. Not failing, but far from healthy. The prognosis: terminal decline unless drastic action is taken.

$2.5T
Total Infrastructure Shortfall
$684B
10-Year Roadway Funding Gap
45,023
Structurally Deficient Bridges
40 years
To Fix Current Backlog at Current Pace

Let those numbers sink in. America faces a $2.5 trillion infrastructure shortfall. Roads and bridges alone need $684 billion over the next decade just to maintain current conditions—not improve them, just prevent further decay. And we're not providing that funding.

2. The Bridge Crisis

As of 2025, 45,023 American bridges are rated "structurally deficient"—meaning they're in poor or worse condition. That's 7.3% of all 618,422 bridges nationwide. If you lined up all the deficient bridges end-to-end, they'd stretch 1,080 miles—the distance from Las Vegas to Seattle.

171.5 Million Daily Crossings

Every single day, American motorists cross these compromised structures 171.5 million times. These aren't obscure rural bridges—they're on routes millions use daily. The average structurally deficient bridge is 68 years old. Many were built during the Interstate construction boom of the 1960s and are now approaching the end of their design life.

The cost to fix them? $125 billion just for bridges alone. Annual spending on bridge rehabilitation: $14.4 billion. Annual spending needed: $22.7 billion. At current rates, it will take 40 years to clear the backlog—assuming no new bridges deteriorate in the meantime (they will).

March 26, 2024: The Wake-Up Call Nobody Heeded

On March 26, 2024, a cargo vessel struck Baltimore's Francis Scott Key Bridge. The bridge collapsed within seconds, killing six workers and severing a major transportation artery. The incident sparked national conversation about infrastructure—conversation that faded within weeks as it always does.

The Key Bridge wasn't structurally deficient. It was struck by a vessel. But the collapse symbolized America's infrastructure vulnerability: one incident, catastrophic consequences, and a realization that thousands of similar structures are one failure away from disaster.

3. The Maintenance Backlog Nobody Tracks

Here's what makes the crisis worse: we don't even know the full extent of the problem. A 2025 Volcker Alliance analysis found that 20 states don't even mention deferred maintenance in their capital budgets. They literally don't track how much maintenance they're not doing.

The states that do track it reveal a crisis: $105 billion in deferred road and bridge maintenance as of 2023, accumulated since 2004. This is debt—not bond debt that appears on balance sheets, but deferred maintenance that will cost exponentially more to fix later than if addressed now.

The Exponential Cost of Delay

Every dollar not spent on maintenance today costs $6-8 in repairs later. A $100,000 road resurfacing project deferred for five years becomes a $600,000 reconstruction. A $1 million bridge repair deferred becomes a $10 million replacement.

America is accumulating compound interest on infrastructure debt—except instead of money, we're paying in collapsed bridges, fatal accidents, and economic losses from congestion and detours.

4. We're Spending More But Getting Less

In 1999, state and local governments spent $50 billion on roads and bridges. By 2023, that had increased to $125 billion—more than double. So why are conditions worsening?

Inflation. The $125 billion spent in 2023 buys only $94 billion worth of construction in 2017 prices. Despite higher nominal spending, the real value of investments has decreased. Construction costs have risen faster than funding, meaning America builds less infrastructure each year even while spending more.

This is the infrastructure death spiral: costs rise, funding stays flat, conditions deteriorate, deferred maintenance accumulates, eventual repairs cost more, which consumes funding that should go to new maintenance, accelerating the cycle.

5. The Federal Government Is Retreating

The 2021 Infrastructure Investment and Jobs Act was supposed to reverse decades of underinvestment. It authorized $1.2 trillion—the largest infrastructure investment in generations. Construction began on 207,000 miles of roadway. Progress seemed possible.

Then the Trump administration returned in 2025. Within months, the White House announced holds on billions in infrastructure funding, including $18 billion for subway and rail projects in New York. The message: states are on their own.

"The political reality is that this administration and this Congress are telling the states, you've got to live much more by your own wits," said William Glasgall of the Volcker Alliance. The federal government, which historically funded infrastructure expansion, is withdrawing just as maintenance costs explode.

Conclusion: Success Has Become Failure

The Interstate Highway System was America's greatest infrastructure achievement. Eisenhower's vision connected the nation, enabled economic growth, and symbolized American engineering prowess. For decades, it worked magnificently.

But success contained the seeds of failure. We built a system so vast that maintaining it requires resources we never allocated. We designed for 50-year lifespans and are now at 60-70 years. We assumed future generations would maintain what we built—and they haven't.

Now America faces a choice: find $2.5 trillion to fix what we built, or watch the Interstate System slowly crumble. Current trends point toward the latter. We're not finding the money. We're not even tracking the full scope of deferred maintenance. We're hoping something changes before catastrophic failures force action.

This is the story of how America's greatest achievement became its greatest liability—and why the bill for decades of deferred maintenance is finally coming due.

In our next paper, we'll examine 2000-2024: Decades of Decay—how we stopped maintaining what we built and why the crisis has been visible for 25 years while we did nothing.
