The layout of Palmerton's streets and alleys is extremely regular, because most of the town was planned and built by the New Jersey Zinc Company. Avenues, which run east to west, contain the majority of addresses and are named for colleges and universities. Streets, running perpendicular, are numbered from First Street in the west to Eighth Street in the east. Most of the houses in the central and southern parts of town (near the zinc plants) are "doubles"—one building divided down the center into two residences.
