Description: The Sulphite Railroad Bridge, locally known as the Upside-Down Covered Bridge, is an historic railroad bridge situated in Franklin, New Hampshire. Constructed around 1896-1897, this bridge was designed to support the tracks of the Boston and Maine Railroad as they spanned the Winnipesaukee River between Franklin and Tilton. This remarkable bridge stands out as possibly the sole surviving "upside down" covered railroad bridge in the United States. In this unique design, the rail bed rests atop the bridge's roof, offering shelter to the trusses beneath. This extraordinary bridge garnered recognition when it was added to the National Register of Historic Places in 1975. However, the Sulphite Railroad Bridge has experienced a period of disuse since 1973, and its current condition is far from ideal. It has fallen victim to various challenges, including graffiti, vandalism, arson, and the impacts of weather.
