It is one of the highway bridges owned by the Commonwealth of Pennsylvania, Department of Transportation, nominated as a multiple resource group.","why_significant":"The nomination argues the bridge is a very good example of early concrete bridge construction that combines traditional and more progressive engineering. Its 70-foot arch is typical of concrete construction in the 1910s, while its rock-faced ashlar wingwalls with concrete balustraded parapets blend stone and concrete techniques. It is noted as one of the few concrete bridges of its type in central Pennsylvania.","narrative":"Built in 1917 over Chest Creek in Westover Borough, Clearfield County, this single-span bridge carries vehicular traffic on a 70-foot open-spandrel concrete arch. Its designer was G. A. Flink and its contractor was Whitaker & Diehl of Harrisburg, as recorded on a bridge plaque. The arch is capped with a continuous solid parapet wall typical of concrete construction in the second decade of the twentieth century. At each end, rock-faced ashlar wingwalls topped with concrete balustraded parapets bring stone masonry into the design, combining older stone craftsmanship with newer concrete methods. The bridge is regarded as a very good example of this blend of traditional and progressive engineering. It is also one of the few concrete bridges of its kind in central Pennsylvania, which is the principal reason it was listed. The nominated area covers the superstructure and substructure within the railings.","period_of_significance":"1917","architect_builder":"G. A.
