History
When routes were first legislated in Pennsylvania in 1911, the present alignment of PA 17 between Ickesburg and Millerstown was designated as part of Legislative Route 191 while the road between Millerstown and Liverpool was designated as Legislative Route 293. PA 17 was first designated in 1928 on its current alignment between US 22 (Market Street) in Millerstown and US 11 in Liverpool. At this time, the entire length of the route was paved. The same year, the road between Ickesburg and US 22 in Millerstown was designated as part of PA 74, which was unpaved. By 1930, PA 74 was under construction between Ickesburg and northeast of Marsh Run and between southwest of Donnally Mills and Millerstown. By this time, the road between Blain and Kistler and to the west of Ickesburg was an unnumbered unpaved road. In the 1930s, PA 17 was extended southwest from Millerstown to PA 274 in Blain along its current alignment, replacing the section of PA 74 between Ickesburg and Millerstown. At this time, the entire length of the route was paved. No major changes have occurred since then.
