Significance: The Walker Bridge is a 330' steel Pennsylvania Petit truss, built in 1893 in Folsom, Sacramento County, California and moved to this site by the California Division of Highways (predecessor to Caltrans) in 1931. The bridge was determined eligible for listing in the National Register under Criteria C (as a very rare and distinguished example of a particular bridge type) and A (for its role as a transportation link at the Klamath River crossing). The appropriate period of significance for the bridge extends from 1893 (when it was built) to 1931 (when it began serving at the current location).
