Atom Buster at the Westinghouse Research Laboratories in Forest Hills, Allegheny County. The Westinghouse Atom Smasher was a 5 million volt Van de Graaff electrostatic nuclear accelerator operated by the Westinghouse Electric Corporation at their Research Laboratories in the borough of Forest Hills. It was instrumental in the development in practical applications of nuclear science for energy production. In particular, it was used in 1940 to discover the photofission of uranium and thorium, and was most cited for certain nuclear physics measurements. The Westinghouse Atom Smasher was intended to make measurements of nuclear reactions for research in nuclear power. It was the first industrial Van de Graaff generator in the world, and marked the beginning of nuclear research for civilian applications. Built in 1937, it was a 65-foot-tall pear-shaped tower. It was essentially unused after World War II, and the main structure was laid on its side in 2015. In 1985, it was named an Electrical Engineering Milestone by the Institute of Electrical and Electronics.

John Farren: I grew up in East Pittsburgh, and every time we drove Rt. 30 going to (or past) Forest Hills, we would see the atom smashers on top of the hill. It was on one side of the highway and Vincent's Pizza was on the other. I hope the developer who tore it down isn't suffering from radiation sickness. It was AN ATOM smasher, after all.

Note that the date on the street view above is 2011. This is what is left.

It appears that today's route for US-30 may have been the original Lincoln Highway route in this area. The next oldest topo map available is 1907, and there was nothing around here back then.
