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.
