Dock Hill Road Extension Stone Arch Bridge
Also known as: Upper Dock Hill Road Bridge
Why it's listed
This small stone arch bridge on Dock Hill Road Extension in Cornwall-on-Hudson, New York, once carried Bay View Avenue over a creek running down from the hills to the west. It is a single elliptical arch of locally quarried stone set in mortar. Finely dressed, hand-tooled ashlar voussoirs form the arch, while the spandrels and low parapet walls are of rougher stone, topped with rectangular copings. No construction records were found, so a date of about 1870 is assigned from comparison with other Hudson Valley stone arch bridges. The builder is unknown. The bridge dates from a period when tourism helped the village grow. It was bypassed when Bay View Avenue was rerouted, after Storm King Highway was completed in the early 1920s, and a Civilian Conservation Corps concrete arch bridge was built just to the west in the 1930s. It is regarded as the most intact 19th-century stone arch bridge in the village and still serves limited traffic and pedestrians.
Significance in brief: The bridge is described as the most intact example of 19th-century stone arch bridge construction in the village, with its bearing arch, spandrel and parapet walls, copings and buttresses largely original. It is significant for architecture as a small-scale example of a bridge type that preceded standardized metal truss bridges, and for transportation as evidence of the village's road improvements in the later 19th century.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
