Pittsburgh PA Pennsylvania Westinghouse Bridge Longest Concrete Span Postcard

This vintage postcard features an aerial view of the Westinghouse Bridge, located east of Pittsburgh, Pennsylvania, on U.S. Highway 30. Notably, the bridge holds the distinction of being the longest concrete span in the world at the time. The image beautifully captures the impressive architectural structure of the bridge alongside a portion of the expansive Westinghouse Plant, which stretches for several miles through the valley.

Printed using Ektachrome technology by Paul M. Penney, this postcard was published by Wonday Film Service, Inc. in Wilkinsburg, Pennsylvania. The card is a standard size (5.5 x 3.5 inches) and is an original paper postcard made by Dexter Press of West Nyack, New York. Its historical significance and depiction of mid-20th century industrial America make it a valuable collectible for enthusiasts of vintage postcards, industrial history, and Pittsburgh landmarks.
