Sulphite Railroad Bridge Underside
Sulphite Railroad Bridge, also known locally as the Upside-Down Covered Bridge is a historic railroad bridge in Franklin. It is located about 0.7 miles east of Franklin, and about 350 yards south of US Route 3, and crosses the river at a point where its banks are quite steep; it is not readily visible from any roadway, but may be seen from the Winnipesaukee River Trail. The bridge is believed to be the only surviving "upside down" covered railroad bridge, in which the rail bed is laid on top of the bridge roof, whose purpose is to shelter the trusses below. The railroad line was shut down in 1973.
