Hill to Hill Bridge, Spans Lehigh River at State Route 378, Bethlehem, Northampton County, PA

Significance: The Hill-to-Hill Bridge was the first bridge to join the boroughs of the City of Bethlehem with a high-level structure eliminating all railroad grade crossings. The structure, constructed almost entirely of reinforced concrete, owed its unusual shape to the eight access ramp structures that fed traffic to the Main Bridge avoiding numerous railroad tracks. The bridge was determined eligible for listing in the National Register of Historic Places as part of the expanded Central Bethlehem Historic District in 1988. The southern part of the bridge is included in the Fountain Hill Historic District. The structure crosses over the Delaware and Lehigh Canal National Heritage Corridor.
