History
When Pennsylvania legislated routes in 1911, the portion of present-day PA 392 along Old Trail Road became part of Legislative Route 250, which ran between York and the Harrisburg area. In 1920, this section of road became part of the Susquehanna Trail, an auto trail running between Baltimore and Williamsport, Pennsylvania. The Susquehanna Trail was designated as PA 4 in 1924. With the creation of the U.S. Highway System in 1926, US 111 became concurrent with PA 4 on the Susquehanna Trail, which was paved. By 1926, Potts Hill Road and Yocumtown Road were unnumbered, unpaved roads. The concurrent PA 4 designation was removed from US 111 in 1928. Potts Hill Road and Yocumtown Road were both paved in the 1930s. US 111 was realigned off Old Trail Road to the parallel I-83 to the west in the 1950s while Potts Hill Road was realigned to head south and intersect Old Trail Road. PA 392 was designated in 1961 to run along its current alignment between PA 177 and PA 262 in order to provide a numbered route at the interchange with I-83 southwest of Yocumtown.
