At 36 feet (11 m) in length, it is the shortest 19th-century covered bridge built for use on a public roadway in New Hampshire that is still standing.

[2] The bridge was listed on the National Register of Historic Places in 1973.

[1] The Prentiss Bridge is located in a rural setting in southern Langdon, spanning Great Brook east of Chester Turnpike, about 0.2 miles (0.32 km) south of its junction with Lower Cemetery Road.

In 1794, the town appropriated funds to build a bridge near the mill of Jabez Rockwell and John Prentiss.

In 1874, the town appropriated $1,000 to replace that structure; the present bridge was presumably built soon afterward.
