"The Starrucca Viaduct of the Erie Railroad Company crosses Starrucca Creek in Lanesboro, Pennsylvania. It is one of the oldest and one of the longest railroad bridges in Pennsylvania. Its 18 slender, semicircular stone arches each span 50 feet and the structure rises 110 feet above the creek.
When built, it was believed to be the most expensive railroad bridge in the world, costing $320,000. Over 800 workers, paid $1 per day, completed the entire bridge in about a year. A half-million feet of cored and hewn timbers were used in the falsework, the temporary wooden framework for supporting the masonry arch rings until the keystones were placed."
wikipedia "Starrucca Viaduct is a stone arch bridge that spans Starrucca Creek near Lanesboro, Pennsylvania, in the United States.... It was the largest stone rail viaduct in the mid-19th century and is still in use...It was designed by Julius W. Adams and James P. Kirkwood and built in 1847-1848 by New York and Erie Railroad, of locally-quarried random ashlar bluestone, except for three brick interior longitudinal spandrel walls and the concrete base portions of the piers and deck covering. This may have been the first structural use of concrete in American bridge construction."
