Pennsylvania Route 39

Pennsylvania Route 39 (PA 39) is a 17.83 miles (28.69 km) state highway located in Dauphin County, Pennsylvania, United States. PA 39 begins at North Front Street near Harrisburg and ends at U.S. Route 322 and U.S. Route 422 near Hummelstown and Hershey. The route passes through the northern and eastern suburbs of Harrisburg and passes by Hersheypark, Giant Center, as well as the primary production factory for The Hershey Company. Between Harrisburg and Manada Hill, it is known as Linglestown Road, from Manada Hill to Hershey as Hershey Road and from Hershey to near Hummelstown and Hershey as Hersheypark Drive. Prior to the establishment of PA 39 in 1937, PA 39, had previously been designated as a route in northeastern Pennsylvania during the 1920s. That designation was deleted when it was renumbered US 11. As a result, PA 39 is one of a few routes which has a set of child routes which are no where near the primary route.

The Linglestown–Manada Hill portion of PA 39 was originally part of Legislative Route 140, one of hundreds of unsigned legislative routes created by the Sproul Road Bill in 1911. LR 140 was later rerouted to bypass Linglestown to the south, and the Paxtonia–Lower Paxton Township portion of its former routing became LR 140A. This legislative route was initially signed solely as PA 894. PA 39 was assigned in the 1930s to the portion of LR 140A east of Linglestown—overlapping PA 894—and also to LR 22006 between the Susquehanna River and Manadahill. The PA 894 designation was later removed.
