Pennsylvania Route 401 (PA 401) is a 20.2-mile-long (32.5 km) east–west state route in Berks and Chester counties, located in southeast Pennsylvania. The western terminus is at PA 23 in Caernarvon Township, across the county line from Elverson. The eastern terminus is at U.S. Route 30 (US 30) in East Whiteland Township, a short distance west of Malvern. PA 401 is called Conestoga Road its entire length and runs through rural areas with suburban development toward the eastern part of the route. PA 401 follows a former turnpike chartered in 1809 known as the Little Conestoga Turnpike. PA 401 was designated along Conestoga Road between PA 29 (Phoenixville Pike) and US 30/PA 1 in 1928. The route was extended west to PA 23 in the 1930s, at which time the entire length was paved.
