Its sister community is Conshohocken, Pennsylvania, located across the Schuylkill River. Montgomery County's seat, Norristown, is located approximately two miles north of, and across the river from, West Conshohocken.
West Conshohocken Borough was incorporated October 6, 1874 from land taken almost equally from the Townships of Lower and Upper Merion. As a river borough, there existed a large number of mills and other industries utilizing water power. The Dougherty Quarry was a prosperous business, producing stone of superior quality known as Conshohocken or Merion Blue. It was much sought after for public buildings, and was shipped by rail throughout the East before supplies were exhausted in the mid-twentieth century.
Today, with its proximity to highways I-76 and I-476 (Blue Route), this small borough and its sister Conshohocken Borough have experienced moderate office and retail development. West Conshohocken is easily identified by the mid and high-rise commercial development along its waterfront, which in recent years has also spread across the river to Conshohocken's waterfront.
