Sandy Hill Bridge, Bridge Street, spanning Hudson River, Hudson Falls, Washington County, NY

Significance: From 1907 to 1908, the Sandy Hill Bridge was the longest multiple span, reinforced-concrete arch bridge in the world. Its design was also the first to employ the use of separately molded concrete blocks for decorative purposes on the exterior spandrel walls, arch rings, and piers. Considering the scope of building a bridge of this magnitude in the infancy of reinforced concrete construction, eight months construction time was in itself a significant achievement.
