Area of Significance: Transporation, Architecture/Engineering
Period of Significance: 1826-1931
The Lehigh Water Gap Chain Bridge Toll House and East Bridge Abutment is significant as it is an important example of a toll house from the early nineteenth century and its strong association with an important river crossing. It successfully illustrates the role toll roads and bridges played in establishing a modern transportation infrastructure in eastern Pennsylvania. In addition, this toll house and the surviving east bridge abutment were once connected with a James Finley chain link suspension bridge, the earliest type of suspension bridge in America. The toll house is also an important example of the vernacular architecture used for toll houses and lock tender houses in eastern Pennsylvania. Nomination provides great supporting documentation.

Area of Significance: Transportation, Politics/Government
Period of Significance: 1926-1929
The three bridges and five road segments are extant discontiguous sections of the original U.S. Highway 25 in South Carolina and are eligible at the local level under Criterion A: Transportation and Politics/Government. U.S. Highway 25 was established in 1926 as one of the original routes of the first federal highway system, a groundbreaking project aimed at bringing government support and coherence to the disjointed and underfunded system of locally and privately managed roadways that crossed the nation. This unique road which followed a historic trading trail reaching back to colonial times also followed the same route as the Carolina Division of the privately designated Dixie Highway and finally converted to the original route of U.S. Highway 25 in S.C. The hard-surfaced concrete road segments and bridges retain their historic integrity from the initial improvement of the highway during the late 1920s. These segments represent the transition from the informal named trail system to a new, standardized highway system overseen by an interstate bureaucracy. They capture a pivotal moment in the nation’s history when the federal government began to assume a more influential role in the improvement of automotive infrastructure.
