In 1875, the Portland and Ogdensburg Railroad completed its line up through Crawford Notch. Passengers thrilled to traverse the Frankenstein Trestle, 520 feet (158 meters) long and 85 feet (26 meters) above the ravine floor, and then the Willey Brook Bridge, 400 feet (122 meters) long and 94 feet (29 meters) high. Later part of the Mountain Division of the Maine Central Railroad, the route is still traveled by the Conway Scenic Railroad.
