Its northern terminus is at US 422 in Palmyra. PA 117 heads west from US 322/PA 72 through forested areas, passing through Mount Gretna before forming a short concurrency with PA 241 in Colebrook. From here, the route heads northwest and intersects US 322 near Campbelltown.

PA 117 continues north through agricultural areas to Palmyra, where it reaches its northern terminus. The route is a two-lane undivided road its entire length. PA 117 was originally designated in 1928 between PA 5 (now US 322) in Campbelltown and US 22 (now US 422) in Palmyra along Palmyra Road and South Railroad Street.
