 This remained in place for only two years , and when the Pennsylvania Department of Highways redesignated highways across the entire commonwealth , the alignment of the U.S. Route 220 portion was redesignated as U.S. Route 111 , while the entire alignment of Route 287 from the Larrys Creek to Tioga was redesignated as Route 84 . The entire alignment of Route 84 consisted of an intersection with U.S. Route 220 in Larrys Creek to U.S. Route 111 in Tioga , where the highway terminated . In 1930 , the concurrent piece of Legislative Route 4 was decommissioned , and the alignment of the highway remained as U.S. Route 111 . The portion from Tioga north remained as Route 111 until 1936 , when the highway was renumbered to U.S. Route 15 .
