PA 514 heading eastbound from the intersection with PA 14 in Troy Township.
PA 514 begins at the intersection with PA 14 south of the borough of Troy, Pennsylvania in Troy Township. The route progresses to the southeast, quickly intersecting with Tennessee Gas Road, where the roadway begins its rural settings. Passing farmland after farmland, PA 514 passes several farms and through trees and enters the community of Granville Summit, where it intersects with Martin Road. In downtown Granville Summit, at the intersection with Cowley Road, the road makes a gradual curve but maintains its southeastern progression. After the curve, PA 514 gains the name Granville Road but remains rural as it continues. The highway makes a curve to the northeast after Spencer Hill Road intersects, where it enters Granville Township.
PA 514 then enters Granville Center, a small hamlet, which stretches until the intersection with Baileys Corners Road (Quadrant Route 3019). After Baileys Corners Road, PA 514 continues eastward until turning to the southeast once again, maintaining its rural surroundings. After the intersection with Sayles Road, the highway makes a gradual curve to the south, intersecting Allen Meadow Road (Quadrant Route 3017). A short distance later, PA 514 enters the hamlet of West Franklin and intersects with PA 414, where the designation terminates.
Route 514 was first designated as a state highway in the mass numbering of state highways around Pennsylvania during 1928 from Route 14, its parent, in Troy to Granville Center. That portion of Route 514 was unpaved for two years until the Pennsylvania Department of Highways upgraded it in 1930. The rest of the alignment, from Granville Center to Route 414 in West Franklin, was still under construction until 1934, when the route was opened to traffic. The route has remained on its current alignment since 1934.
