Sacketts Brook Stone Arch Bridge, Stone arch bridge in Putney, United States

Sacketts Brook Stone Arch Bridge spans Sacketts Brook in a wooded ravine just east of Putney village center. Its single segmented arch, 29 feet long, is built of mortared granite blocks with a slightly projecting keystone and rises about 12.5 feet above the stream. The roadway is 15.5 feet wide, and the abutments and wing walls are unmortared rubblestone.

The bridge was built in 1906 by stonemason James Otis Follett, who created over 40 bridges and culverts during his career. Today it remains one of only 11 surviving structures from Follett's extensive body of work.

Locals call it the Hi-Lo Biddy Stone Arch Bridge, a name tied to the truncated road that once crossed it. The roadway is now cut off at both ends, so the span serves as a foot crossing over Sacketts Brook in its wooded ravine. The arch springs from mortared granite blocks with a slightly projecting keystone, while the abutments and wing walls are dry-laid rubblestone.

The bridge sits about 0.25 miles (0.40 km) east of United States Route 5, reached by turning onto Mill Street; the old road is now truncated at both ends. The span is a single lane 15.5 feet (4.7 m) wide, closed to vehicles since 1996. A 2000 report noted erosion threatening the abutments and wing walls, so approach the stonework with care.
