The Story
John A. Roebling was a German-born engineer whose faith in twisted wire cable transformed how Americans crossed their rivers. Here in Pittsburgh in 1846 he built one of the first wire-rope suspension bridges to carry a road over the Monongahela, proving a design he would refine across the country. His genius culminated in the Brooklyn Bridge, whose plans he drew before his death in 1869 left its completion to his son Washington.
Why it matters
Roebling's wire-rope suspension bridges revolutionized American civil engineering, linking cities and enabling the monumental spans that defined the industrial age.

Westinghouse Railroad Air Brake
Pittsburgh, PA · est. 2011
In 1869 a young inventor named George Westinghouse solved one of railroading's deadliest problems: how to stop a long train quickly and safely. His compressed-air brake let an engineer halt every car at once instead of relying on brakemen scrambling car to car. From this building his company grew into an industrial giant, and the technology he pioneered still slows trains around the world today.
Davis Island Lock & Dam
Avalon, PA · est. 1987
In the decades after the Civil War, the U.S. Army Corps of Engineers set out to tame the Ohio River for year-round navigation. Their first lock and dam on the river, built here between 1878 and 1885, was a marvel of its day—the largest movable dam yet constructed, with the world's first rolling lock gate and its widest lock chamber. It served until 1922, when the nearby Emsworth Locks and Dams replaced it.
George Westinghouse
East Pittsburgh, PA · est. 1948
George Westinghouse was one of the towering inventors of America's industrial age, credited with the railroad air brake and some four hundred other patents. From his base in Pittsburgh he championed alternating-current electricity, the system that won the 'War of the Currents' and made it possible to transmit power across long distances. The company he founded turned his ideas into an industrial empire that helped electrify the modern world.
Steamboat "New Orleans"
Pittsburgh, PA · est. 2011
On October 15, 1811, the side-wheeler New Orleans slid into the Monongahela near Suke's Run — the first steamboat ever built west of the Alleghenies. Its launch proved that steam power could conquer the powerful currents of the Ohio and Mississippi, and Pittsburgh, already rich in iron and timber, quickly became a bustling yard for building the boats that carried a nation west.
