The United States has 707 bridges in Florida built before 1951 that remain in active service.

About Historic Bridge Data

Bridges built before 1951 are classified as historic in this database. Many were designed to 1940s standards with lower load limits and narrower lanes. While FHWA requires regular inspections of all bridges regardless of age, older structures often require more frequent monitoring and rehabilitation investment.
