Built in 1885, it carries Old County Farm over Whiting Brook, just south of its northern junction with Burton Highway in a rural section of northwestern Wilton.

It is an unusually late and well-preserved example of a 19th-century stone arch bridge, and was listed on the National Register of Historic Places in 1981.

The bridge consists of a single stone arch with a span just under 18 feet (5.5 m).

[2] The bridge was built in 1885 for the town by the Ward brothers of Lowell, Massachusetts, at a cost of $3,000.
