In 1967, US 30 was shifted to a freeway bypass between Prospect Road east of Columbia and east of Lancaster; PA 462 was designated onto the former alignment of US 30 between those two points. In 1972, PA 462 was extended west to its current terminus at US 30 west of York after US 30 was shifted to a bypass between west of York and Columbia. In the 1970s, the route was widened to a divided highway near the PA 24 intersection. The westbound direction of PA 462 in Lancaster was shifted from Orange Street to Walnut Street, running concurrent with PA 23, in the 1970s. In York, the eastbound direction of PA 462 was originally planned to be shifted to Princess Street as part of constructing Continental Square at the intersection of Market and George streets; however, it remained along Market Street.
