State highway in Dauphin County, Pennsylvania, United States

Pennsylvania Route 39 (PA 39) is a 17.83 mile (29 km) state highway located in Dauphin County, Pennsylvania, United States. PA 39 runs from North Front Street near Harrisburg east to U. S. Route 322 (US 322) and US 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. PA 39 was extended southward to the vicinity of Hummelstown in two stages. The first extension during the mid 1940s shifted PA 39's eastern terminus to the junction of Hershey Road and Allentown Boulevard (US 22) south of Manadahill. Its terminus was moved to its present location in the early 1960s. Only local realignments and improvements have occurred since.

PA 39 begins at an intersection with North Front Street on the east bank of the Susquehanna River in Susquehanna Township, Dauphin County, north of the city of Harrisburg. It heads northeast as Linglestown Road through a densely populated neighborhood known as Lucknow, with the Capital Area Greenbelt trail following the road, and widens from two to four lanes as it passes over Norfolk Southern Railway's Pittsburgh Line. The trail splits south at the Industrial Road intersection before PA 39 approaches an interchange with the US 22/US 322 freeway at the northern tip of Wildwood Lake. East of the exit, the highway reverts to two lanes and passes through the predominantly residential northern suburbs of Harrisburg. It intersects North Progress Avenue prior to passing into Lower Paxton Township. West of the village of Linglestown, Linglestown Road intersects Colonial Road, and then continues east to Linglestown, where it intersects North Mountain Road at a roundabout. Outside of the village, the amount of development along the highway declines as the route passes through areas of forests and open fields, crossing Beaver Creek. Continuing east, the road becomes more developed as it approaches an interchange with Interstate 81 (I 81) at exit 77. Just east of the interchange, PA 39 intersects Jonestown Road and changes names from Linglestown Road to Hershey Road. LR 140 was realigned by 1926 to follow a direct route between Paxtonia and Manadahill via Jonestown Road. The portion of former LR 140 from Paxtonia to the Lower Paxton–West Hanover township line was then redesignated as LR 140A. All of LR 140A was designated as the signed PA 894 by 1930. In the Omnibus Road Bill Act of 1931, LR 22006 was established, spanning the portion of current PA 39 from the Susquehanna River north of Harrisburg to Hanoverdale at the West Hanover–South Hanover township line, three miles north of Union Deposit. The remainder of current PA 39 north of Swatara Creek was a state aid route designated A 306, which ran from South Hanover Township to Union Deposit. Those sections of roads were paved in 1926, in preparation for gaining state aid.

PA 39 was assigned on May 1, 1937, by the Pennsylvania Department of Highways to the portion of LR 22006 between the Susquehanna River (at North Front Street) and Manadahill and to the section of LR 140A east of Linglestown, overlapping PA 894 along the latter. PA 894 was also extended northward along Piketown Road to a junction with PA 443 near Piketown. Two years after PA 39 was assigned, the Harrisburg Regional Planning Commission issued a report drafted by Harrisburg city planner Malcolm H. Dill that addressed transportation needs for the Harrisburg region. The Dill plan proposed rerouting US 22 along Linglestown Road from Harrisburg to Manadahill, replacing PA 39. Ultimately the Dill plan was not selected by PennDOH and PA 39 was not deleted.

The first change to PA 39's routing came in the 1940s. During this time, US 22 was rerouted through Dauphin and Lebanon counties to follow Allentown Boulevard instead of Jonestown Road. As a result, PA 39 was extended a short distance southward along LR 22006 on what is now Jonestown Road, Harper Drive, and Hershey Road to meet the new alignment of US 22 south of Manadahill. The portion of Hanover Street south of Canal Street (between Canal Street and West Derry Road today part of Hersheypark Drive) had previously been part of PA 340 from the 1930s to the early to mid 1950s. The portion of the route between Old Chocolate Avenue and Walton Avenue near Hummelstown and Hershey had previously been part of US 422 from 1927 to 1952. Park Boulevard in Hershey was rerouted in 1973 to intersect the new bypass and provide a direct connection between Hersheypark and PA 39.

In the early 1970s, the portion of PA 39 in Susquehanna Township from North Sixth Street to Laurelwood Drive was converted from a two lane roadway to a four lane divided highway as part of the construction of the US 22/US 322 bypass. To the southeast, the segment of PA 39 south of West Chocolate Avenue near Hummelstown was rebuilt as a divided highway ca. 1990. All of Hersheypark Drive east to Laudermilch Road was converted into a divided highway by 1995. At the same time, West Hanover Township made improvements to the area surrounding PA 39's interchange with I 81. Prior to the improvements, there was only one traffic light in the vicinity, located at Jonestown Road. Several traffic lights and two additional lanes with a center concrete barrier was added to handle the increased truck traffic caused by the construction of warehouses nearby in 2003 and 2004. PA 39 was also improved in Linglestown square, when two roundabouts were installed between 2009 and 2011.
