111 Alt. became concurrent with PA 24 as North Duke Street northbound and North George Street southbound. Past North Street, US 111 Alt./PA 24 continued north along two-way North George Street, crossing the Codorus Creek. The two routes headed north out of York and continued to an interchange with I-83/US 111. Here, US 111 Alt. ended while PA 24 continued to the north. US 111 Alt. was designated in the 1950s after US 111 was rerouted to bypass York to the east along I-83. The alternate route ran along the former alignment of US 111 on George Street in York, while the southern portion followed a new highway connecting I-83/US 111 to George Street. US 111 Alt. was decommissioned in the 1960s concurrent with US 111 being decommissioned in favor of I-83; the former alignment of US 111 Alt. was renumbered to I-83 Bus.
