Before the creation of the U.S. highway system, the route had been part of PA 29 between the Delaware state line and West Chester and PA 52 between West Chester and the New Jersey state line. US 122 was created in 1926, connecting US 22 at Whitehouse, New Jersey, with Wilmington, Delaware. In 1934, US 122 became part of US 202. US 202 followed a different alignment in Chester County before the freeway alignment was built. The former alignment had US 202 separating from US 322 and the West Chester Bypass onto Paoli Pike to Paoli, then overlapping US 30 in Paoli and then turning north on what later became PA 252. In the early 1960s, a four-lane freeway was proposed that would follow the US 202 corridor. The "Piedmont Expressway" was to be long, and would cost approximately $146 million. It was to serve as an outer beltway around the Philadelphia area, similar to the Capital Beltway that encircles Washington, D.C. The Pennsylvania Department of Transportation (PennDOT) divided the proposed US 202 freeway into the following eight sections: Section 100: Concord Township, Delaware County, to West Goshen Township, Chester County (approximately eight miles) Section 200: West Goshen Township, Chester County, to West Whiteland Township, Chester County (approximately six miles) Section 300: East Whiteland Township, Chester County, to Tredyffrin Township, Chester County (approximately seven miles) Section 400: Tredyffrin Township, Chester County, to Upper Merion Township, Montgomery County (approximately five miles) Section 500: Upper Merion Township, Montgomery County, to Norristown, Montgomery County (approximately five miles) Section 600: East Norriton Township, Montgomery County, to Montgomery Township, Montgomery County (approximately nine miles) Section 700: Montgomery Township, Montgomery County, to Doylestown Township, Bucks County (approximately nine miles) Section 800: Doylestown Township, Bucks County, to New Hope, Bucks County (approximately ten miles) The US 202 parkway was proposed as an at-grade road that would run from Montgomeryville northeast to Doylestown. The road was at the front of discussion and controversies around Bucks and Montgomery counties for almost forty years. It was originally planned as a four-lane freeway, but in 2005 the plan was changed to a two- to four-lane parkway after funding for the road was cut. Construction began in November 2008 on the portion between PA 63 and PA 463, with construction on the portion from PA 463 to the interchange with PA 611 following in January 2010. Completion of the parkway was initially
