This four-mile trail is along an asphalt path that was once a railbed. The trail goes through Shelby and ends at a bridge across Silver Creek.  The trail is named for its stone arch bridge. The bridge is only one of four 30' arch culvert bridges and is named the first railroad structure built in Shelby County. Most railroad bridges in Iowa were wood or timber, but limestone for the trestle was believed to have come from a quarry in Earlham, Iowa, not far from the railroad’s mainline in that area.
