The section of the current route east of Lancaster was built as a turnpike called the Philadelphia and Lancaster Turnpike in 1794, which headed east to Philadelphia. By 1796, a road continued west from Lancaster across the Susquehanna River to York. The state took over the turnpike in the beginning of the 20th century. In 1913, the road between York and Lancaster was incorporated into the Lincoln Highway, an auto trail that ran from San Francisco to New York City. The Lincoln Highway through Pennsylvania became PA 1 in 1924. US 30 was designated concurrent with PA 1 west of Philadelphia in 1926, with the PA 1 designation removed two years later. US 30 was widened into a multilane road between York and Lancaster in the 1930s. The route was moved to one-way pairs in Lancaster in the 1930s, following King Street eastbound and Orange Street westbound, and York in the 1950s, following Market Street eastbound and Philadelphia Street westbound. In 1967, US 30 was moved to a freeway bypass between Prospect Road east of Columbia and east of Lancaster, with the former alignment becoming PA 462. US 30 was realigned to a freeway between York and Columbia in 1972 and PA 462 was extended west along the former alignment to west of York. In the 1970s, westbound PA 462 was moved from Orange Street to Walnut Street in Lancaster.
