The Risser's Mill Covered Bridge or Horst's Mill Covered Bridge was a covered bridge that spanned Little Chickie's Creek in Lancaster County, Pennsylvania, United States. It was burnt by an arsonist on July 8, 2002. As of October, 2006, a concrete bridge is being built 100 feet north of the site of the bridge. Plans exist to rebuild a replica of the bridge on the original hand-laid stone bridge abutments.
