The area was originally named St. Clair Township in 1763, and the southern part was split off as Upper St. Clair Township in 1806. For nearly 100 years, Bridgeville was a village within Upper St. Clair Township, known for its one bridge over Chartiers Creek where people frequently met to trade goods. An old saying, "Meet me at the bridge," provided an obvious name for the village that began to develop north of the bridge around 1830.
A mass shooting took place on August 4, 2009, in an LA Fitness health club near Bridgeville in Collier Township. The attack resulted in four deaths, including that of the perpetrator, who took his own life. Nine other people were injured.
