This bridge is perhaps one of, if not the most well-known of the many historic Allegheny County bridges that does not cross one of the big three rivers. Crossing Turtle Creek and other features as a high level bridge, this bridge was claimed to be the longest concrete arch bridge in the world when completed. Such a claim would have to exclude railroad bridges, since the older Tunkhannock Viaduct far exceeds the length of this bridge. Regardless, the bridge was and remains among the longest concrete arch bridges in the United States. However, the Westinghouse Bridge's largest central span does appear to have been the longest concrete arch span in the world when completed. The Pittsburgh area is noted for a number of concrete arch bridges with unusually long span lengths, yet the 460 foot length of this bridge's central span dwarfs all others in the Pittsburgh area. In addition to the length of the bridge, the height of the bridge, about 200 feet above the valley floor, adds to its significance and impressive appearance.
Of interest, this enormous bridge was not designed by an outside consulting engineer as was often the case with large, complicated bridges. Instead, Allegheny County Engineer Vernon Covell with the assistance of George Richardson designed the bridge. This bridge was constructed by Booth and Flynn Company. Visit the Ohio River Boulevard Spruce Run Bridge for photos, information, and biographies about the company and the important men who who ran it.
This bridge is apparently officially named the "George Westinghouse Memorial Bridge" even though the pillars at the ends of this bridge read simply "George Westinghouse Bridge." The bridge is commonly called the Westinghouse Bridge for short.
This bridge also includes enormous decorative pylons that depict area history through a series of sculptures. There are also sculptures showing the Allegheny County coat of arms. The four descriptive sculptures and the text below each sculpture is shown below.
