PA 401 begins at an intersection with PA 23 in Caernarvon Township, Berks County, heading southeast on two-lane undivided Conestoga Road. The route heads into agricultural areas as it crosses into the borough of Elverson in Chester County, where it runs between farmland to the north and rural areas of woods and homes to the south, crossing PA 82. After this junction, the road runs between housing developments to the north and rural areas to the south, crossing into West Nantmeal Township. PA 401 continues into forested areas with some farm fields as it enters East Nantmeal Township and comes to the PA 345 intersection. At this point, the route continues southeast through more woods before heading into farmland and turning south. The road crosses into forests and turns sharply to the east, entering areas of farms with a few residences. Farther east, PA 401 heads into more wooded areas of homes as it crosses into West Vincent Township and reaches the PA 100 junction.[2][3]
The route continues southeast past a mix of farms, woods, and housing developments, briefly crossing into Upper Uwchlan Township before heading back into West Vincent Township. The road curves south before continuing southeast into West Pikeland Township, where it crosses Pickering Creek before intersecting PA 113. Past this intersection, PA 401 passes through wooded areas of residential development, passing under the Pennsylvania Turnpike (Interstate 76). A short distance later, the route comes into Charlestown Township and passes more forested areas of homes before turning east into East Whiteland Township. The route runs past more housing developments and crosses Valley Creek before it widens to four lanes at the Phoenixville Pike intersection and reaches a diamond interchange with the US 202 freeway, where it is briefly a divided highway. The route narrows back to a two-lane undivided road past this interchange and crosses the Chester Valley Trail before continuing southeast to the eastern terminus at US 30 (Lancaster Avenue) in Frazer.[2][3]

A turnpike called the Little Conestoga Turnpike was chartered on March 16, 1809 to run from the Philadelphia and Lancaster Turnpike near the Warren Tavern in Malvern northwest toward Berks County, where it intersected a junction between roads leading to Morgantown and Reading.[4] When Pennsylvania first legislated routes in 1911, the current route of PA 401 was not legislated as a route.[5] PA 401 was designated in 1928 to run along Conestoga Road between PA 29 (Phoenixville Pike) and US 30/PA 1 while the road west from PA 29 to PA 23 remained unnumbered. At this time, the entire length of Conestoga Road, including the part designated PA 401, was unpaved.[6] During the 1930s, PA 401 was extended west along Conestoga Road from PA 29 to its current western terminus at PA 23. At this time, the entire length was paved.[7] PA 401 has remained on the same alignment since.[3]
