Clark's Bridge is a Howe Truss bridge built in 1904, weighing 200 tons, with a capacity of 200 tons, a length of 116 feet, a width of 21 feet 8 inches, and a clearance of 20 feet 6 inches. It originally spanned the Winooski River in Barre, Vermont, was disassembled in 1960 and moved to Lincoln, and was reassembled and returned to service in 1966. It is now part of the White Mountain Central R.R. Logging Museum and is the world's last Howe Truss covered R.R. bridge still in use. Edward M. Clark served as curator and project engineer, and the bridge is eligible for listing on the National Register of Historic Places as New Hampshire Bridge No. 64.
