was created on May 31, 1911, through the Sproul Road Bill, which established the initial set of legislative routes throughout Pennsylvania. LR 140 entered Linglestown on North Mountain Road, then turned to follow modern PA 39 from Linglestown to Manadahill, where it veered onto Jonestown 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. Designation 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. The overlap between PA 39 and PA 894 was eliminated in the 1940s when the entirety of the PA 894 designation was removed. 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. Extensions The first change to PA 39's routing came in the 1940s. During this time, US 22 was rerouted through Dauphin and Lebanon County 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.
