Waldo Covered Bridge

The Waldo Covered Bridge, also known as the Riddle Mill Covered Bridge, is a privately owned wood & metal combination style covered bridge that spans Talladega Creek in Talladega County, Alabama, United States. It is located off State Route 77 just south of the town of Waldo, about 6 miles (10 kilometers) southeast of Talladega.

Built in 1858, the 115-foot (35 m) bridge is a combination of Howe truss and Queen-post truss construction over a single span. Its WGCB number is 01-61-02. The Waldo Covered Bridge is one of five existing covered bridges in Alabama built before 1950 not listed on the National Register of Historic Places and the only one left unmaintained. It is the second oldest surviving covered bridge in the state.
