Fascinating facts about America's bridge infrastructure

Massive Daily Traffic

Americans cross bridges approximately 5.0B times every single day. That's roughly 15 crossings per person daily.

Aging Infrastructure

The average American bridge is 48 years old. Many bridges were designed for a 50-year lifespan, meaning a significant portion of our infrastructure is approaching or has exceeded its designed service life.

Bridges in Distress

Approximately 41,685 bridges (6.7%) across the country are rated as structurally deficient or in poor condition, requiring significant repair or replacement.

Sufficiency Ratings

Every bridge is scored on a 0-100 scale called the Sufficiency Rating, evaluating structural adequacy, functionality, and how essential the bridge is to the public. The national average sits at 63.6.

Coast to Coast

The NBI tracks bridges in all 50 states, the District of Columbia, and U.S. territories. From rural single-lane crossings to massive interstate highway overpasses, every public bridge over 20 feet is cataloged.

Open Data

All data comes from the National Bridge Inventory maintained by the Federal Highway Administration. The NBI is updated annually and represents one of the most comprehensive infrastructure datasets in the world.
