North of Millbach, U.S. 422 follows the route of the early-nineteenth-century turnpike that linked Lebanon with Harrisburg and Reading. Here, off PA 419, the landscape is free of billboards and commercial ephemera, making it possible to focus on the working farms and small villages that are nearly as they were a century ago. German architectural heritage forms a continuous skein of motifs across Pennsylvania from Bethlehem on the east to Economy village on the west.
