 A small portion of Port Republic Road through Port Republic was included in the state highway system by the late 1920s as part of the highway between Waynesboro and Elkton.This section was paved in the early 1930s and carried three different route numbers until it was transferred to the secondary system in the early 1940s.Port Republic Road was placed on its modern alignment through Port Republic in the mid-1950s, by which time almost all of the highway was paved.
