Description
Glass lantern slide of a black and white photograph of the Columbia Railroad Bridge over the Schuylkill River in Philadelphia taken on October 25, 1921. The photograph looks west across the span of the bridge showing the four rail tracks that cross the bridge. Kelly Drive is visible passing under the first arch of the bridge. The far side of the river is lined with trees and the Belmont Pumping Station and its smokestacks are seen behind them. The Columbia Railroad Bridge is a concrete arch bridge over the Schuylkill River in Philadelphia consisting of eight concrete arch spans supporting four railroad tracks and a pedestrian walk. It was designed by Samuel Tobias Wagner who was chief engineer of the Philadelphia & Reading Railway at the time and is the third railroad bridge at this location. It opened in 1920 with two tracks, and the other two were added in 1921. Used to illustrate the course "Civil Engineering Structures" which was taught between 1893-1950 at the Wagner Free Institute of Science, Philadelphia, Pa.
