Ambridge Heights, PA

Ambridge Heights is a census-designated place in Harmony Township, Beaver County, sitting inside the older Economy-Ambridge story. The Harmony Society established Economy in 1824, and the settlement's remnants are preserved at Old Economy Village. Nearby Ambridge grew around the American Bridge Company, whose steel plant began construction in 1903. Ambridge Heights itself was first defined as a census place in 2023, so its official map is new even though the surrounding history is not. Locally, the useful frame is Harmony Township, the Ohio River corridor, and the old Economy industrial landscape.
