Bridges Built Before 1951
The United States has 1,333 bridges in Wisconsin built before 1951 that remain in active service.

About Historic Bridge Data

While FHWA requires regular inspections of all bridges regardless of age, older structures often require more frequent monitoring and rehabilitation investment.
