States Facing the Greatest Bridge Repair Needs

Which states have the most bridges in poor condition? We rank every state by the scale of its bridge repair challenge, from total poor bridges to poor-condition percentage.

By BridgeStats Data Team

The Bipartisan Infrastructure Law (2021) dedicated $40 billion to bridge repair and replacement -- the largest such investment in U.S. history. But that money is not distributed equally. States with more poor-condition bridges receive proportionally more federal funding under the Bridge Formula Program. Understanding which states face the greatest repair burden helps explain where that money is going and why.

Nationally, 41,685 bridges (6.7%) are rated in poor condition. But some states carry a far disproportionate share of that total.

Count vs. Percentage

It is important to distinguish between the *number* of poor bridges and the *percentage*. A state like Texas, with one of the largest bridge inventories in the country, may have more poor bridges by raw count but a lower poor-condition percentage than a smaller state with a concentrated aging problem. Both metrics matter: the count tells you the scale of the repair task, while the percentage tells you how broadly the problem affects the state's network.
