It was built by T.S. Christian and is a structure in the county's historic transportation network.","why_significant":"The nomination argues the bridge is significant under engineering and transportation. It uses a queen post design, which the form notes was used for longer spans in Columbia County, and it belongs to a group of covered bridges that the form says have not been built in the county in the last half century. Covered bridges served farming, saw and grist mill traffic as towns grew.","narrative":"Located in Millville, Columbia County, Pennsylvania, the Creasyville Covered Bridge is a short queen post structure measuring 44.5 feet in length, with a roadway 14 feet wide and 11 feet of clearance. T.S. Christian is recorded as its builder. The bridge has board and batten side walls and a herringbone floor carrying two runways. Its undergirding has no added steel beams. The original stone and mortar abutments were replaced with concrete. Oak, pine, or hemlock was the usual lumber for bridges of this kind. Covered bridges were built in Columbia County as towns grew and travel between farms, saw mills, and grist mills increased. Because the county has built few covered bridges in the last fifty years, the form regards the engineering of surviving examples as distinctive. Its significance lies in transportation history and in the design of the structure itself.","period_of_significance":null,"architect_builder":"T.S.
