Oldest Bridges in America

The United States has thousands of bridges that have stood for over a century. Many of these historic structures are still in active use, carrying modern traffic loads they were never designed for. The bridges below are the oldest in the National Bridge Inventory, ranked by year built. While age alone doesn't determine condition, older bridges often require more frequent inspection and maintenance.

A bridge's longevity depends on its construction material, maintenance history, and the loads it carries. Stone arch bridges from the 1800s can outlast steel truss bridges from the 1950s if properly maintained. Click any bridge to see its full inspection history and current condition rating.
