Question: Which town has a lower population, Hummelstown or Hershey? Passage:The eastern section of US 422 begins at a partial cloverleaf interchange with US 322 and the eastern terminus of PA 39 east of the borough of Hummelstown in Derry Township, Dauphin County, heading northeast as a four-lane divided highway. The road passes commercial development along with some farm fields and residential development as it heads into the community of Hershey, where it becomes West Chocolate Avenue. The route heads into a mix of homes and businesses and turns east-northeast, where it narrows to a two-lane undivided road. At this point, West Chocolate Avenue becomes lined with street lamps that are shaped like Hershey's Kisses. US 422 continues along West Chocolate Avenue and comes to an intersection with PA 743 at Cocoa Avenue in the center of Hershey. At this point, the route becomes East Chocolate Avenue, a three-lane divided with two eastbound lanes and one westbound lane that passes southeast of the Hershey Chocolate factory. The road becomes undivided, still with two eastbound lanes and one westbound lane, and passes near a few residences and businesses as it heads between two golf courses, narrowing to two lanes. US 422 runs past more residential and commercial development, leaving Hershey and heading through the community of Palmdale.
