The Wire Suspension Bridge spanning the Carrabassett River in New Portland is a unique structure—it's the only survivor of four such bridges built in Maine in the 1800s and probably the only such bridge still standing in the United States. The bridge was begun in 1864 and completed in 1866. David Elder and Captain Charles B. Clark were responsible for the design and construction of the bridge.
The towers are constructed of timber framing and covered with boards protected by cedar shingles. The bridge was renovated in 1961, when the tower bases were capped with concrete, the towers were rebuilt, steel suspender rods were replaced by steel cables, and a new timber deck was installed. The tower framing timbers and main support cables are the original material. The span between towers is 198 feet.
