Packerville Bridge is a historic stone arch bridge carrying Packerville Road over Mill Brook in Plainfield, Connecticut. It is a masonry arch bridge with cut-stone barrel and rubble spandrels with a span of 26 feet (7.9 m) and a total structure length of 31 feet (9.4 m). The bridge was built in 1886, after a major flood washed away most of the town's bridges. It is a well-preserved example of vernacular 19th century masonry bridge technology. The bridge was added to the National Register of Historic Places in 1992, at which time it was one of about 20 surviving stone-arch bridges in the state.
