This change was made to provide the same route number on both sides of the I-81 interchange north of Harper Tavern. The route was realigned to head north and intersect PA 72 and PA 443 within the Pennsylvania National Guard's Edward Martin Military Reservation in the late 1960s, following Fisher Avenue and Asher Miner Road. In the 1970s, the northern terminus of PA 934 was cut back to its current location at the I-81 interchange.
