Hal W. Adams Bridge, Suspension bridge in Mayo, United States.

The Hal W. Adams Bridge is a suspension bridge carrying State Road 51 across the Suwannee River, linking Lafayette and Suwannee counties three miles north of Mayo, Florida. Built in 1947, it was the first suspension bridge in Florida and the only one to carry highway traffic.

Built in 1947, the Hal W. Adams Bridge was the first suspension bridge constructed in Florida and the only one ever to carry highway traffic. It opened on July 4, 1947, and was named for Hal W. Adams of Mayo, a former Lafayette County judge and longtime circuit judge for the circuit covering Lafayette and Suwannee counties. In 1989 it was listed in A Guide to Florida's Historic Architecture, published by the University of Florida Press.

The bridge is named for Hal W. Adams of Mayo, a former Lafayette County judge who then served as circuit judge for the circuit covering Lafayette and Suwannee counties. The naming took place at the bridge's opening on July 4, 1947, so the dedication and the first crossing happened on the same day.

The bridge carries State Road 51 across the Suwannee River on the county line between Lafayette and Suwannee counties, 3 miles north of Mayo. Drivers cross it directly on the highway; there is no separate pedestrian path mentioned in the sources.
