Sewickley historical society presents ‘Golden Age of Bridge Building’

Wednesday, April 24, 2019 | 6:00 AM

Gerry Kuncio will present “The Golden Age of Bridge Building” at 7:30 p.m. today at the Old Sewickley Post Office.

From 1924 to 1940, the Allegheny County Department of Public Works erected hundreds of bridges, one of the largest infrastructure improvement programs ever undertaken by a Pennsylvania municipality. The bridges included engineering masterpieces that have become signatures of the county’s modern landscape, such as the “Three Sisters” across the Allegheny River, and the West End, McKees Rocks, Liberty and Westinghouse Memorial bridges.

This Golden Age of bridge building cemented Pittsburgh’s reputation as the “City of Bridges” and developed infrastructure that helped knit the city and county together. This presentation examines the bridge program and the political fallout. It highlights how and why some of Pittsburgh’s best-known bridges were built and how bridges, in this case, both unified and divided the county.

Kuncio, senior historian at Skelly and Loy engineering-environmental consultants, has worked as a non-academic historian for nearly 30 years, including time with the Pennsylvania State Historic Preservation Office and the Historic American Engineering Record.
