39 was rerouted in 1969 when a new road was constructed between Jonestown Road and Manada View Drive which directly connected Linglestown Road to Hershey Road. The alignment on Jonestown Road and what became Harper Drive was deleted. PA 39 was extended further southward on LR 22006 and A-306, as well as parts of Legislative Routes 22011 and 22013, in 1961, to a new terminus at US 322 and US 422 near Hummelstown. At the time, it was routed on Hanover Street in the vicinity of Union Deposit. 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. A new highway around the eastern fringe of Union Deposit was constructed in 1968 and opened to traffic as a realignment of PA 39, later that year. Park Boulevard in Hershey was rerouted in 1973 to intersect the new bypass and provide a direct connection between Hersheypark and PA 39. Rehabilitation projects 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. The divided highway was extended west to North Front Street in the early 1990s. 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. The piece of PA 39 near I-81 was reconstructed into a four-lane divided roadway ca. 1990. In 2009, PA 39 was widened to five lanes (two lanes in each direction with a center turning lane) when a new shopping center near the intersection of PA 39 and Progress Avenue was built. 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
