Catherine Carroll Shelley was a midwestern United States railroad heroine and the first woman in the United States to have a bridge named after her, the Kate Shelley High Bridge. She was also one of the few women to have a train named after her, the Kate Shelley 400.

The Kate Shelley High Bridge, officially called the Boone Viaduct when it was completed in 1901, is one of the highest and longest double-track railroad bridges in the United States. It is located approximately 3 miles (4.8 km) west of Boone, Iowa.
