The Union Railroad Port Perry Bridge is a truss bridge that carries the Pennsylvania Union Railroad across the Monongahela River between Duquesne, Pennsylvania and the former town site of Port Perry in North Versailles, Pennsylvania.[1] [2] Industrial pipelines adorn the bridge, conveying coke oven gas produced at U.S. Steel's Clairton Coke Works to the company's Edgar Thomson Steel Works near the north end of the bridge for use as fuel.
