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. Unlike Linglestown Road, which followed a mostly east–west alignment, Hershey Road has a north–south orientation. It heads south from Jonestown Road to intersect US 22, here an at-grade roadway named Allentown Boulevard, near Skyline View. Hershey Road continues onward, snaking southeastward through a rural region of Dauphin County to the vicinity of Hershey. During this stretch, it passes through South Hanover Township and serves the communities of Hanoverale and Union Deposit. The route crosses into Derry Township after crossing over Swatara Creek, then intersects Hersheypark Drive near the creek's southern bank. Hershey Road continues south from here as Park Boulevard, a service road for the Hersheypark amusement park, Hersheypark Stadium, Hersheypark Arena, The Star Pavilion, Giant Center (where the Hershey Bears of the American Hockey League play), and Hershey's Chocolate World; however, the route veers westward onto Hersheypark Drive and bypasses Giant Center to the north. This portion of the road is four lanes wide, the first significant portion of PA 39 to be that many lanes wide since the area surrounding I-81. PA 39 heads south bypassing the village of Hershey to the north and west. It passes under Norfolk Southern Railway's Harrisburg Line, then enters a highly developed area east of the borough of Hummelstown. Here, the road intersects Walton Avenue, a local street connecting Hersheypark Drive to the village. This is the final junction along PA 39 as the route ends later at a modified cloverleaf interchange with US 322 and US 422.
