The Deer Isle Bridge encountered wind stability problems that were similar to a bridge found in which U.S. state?
Deer Isle Bridge The Deer Isle Bridge is a suspension bridge spanning Eggemoggin Reach in the state of Maine. The bridge is the only vehicular connection from the Maine mainland to Little Deer Isle, one of the segments that make up the island. The span was completed in March 1939 with a main span of 329 meters (1,088 ft). The bridge was designed by Holton Duncan Robinson and David Bernard Steinman. It encountered wind stability problems that were similar to those of the Whitestone Bridge and the original Tacoma Narrows Bridge, which collapsed shortly after it opened. The problems led to modifications which included numerous cable stays connecting cables to the tower and tower to the deck. The span today carries two narrow lanes of State Route 15.
Cold River Bridge (Langdon, New Hampshire) The Cold River Bridge, also known as McDermott Bridge, is a historic wooden covered bridge over the Cold River in Langdon, New Hampshire, USA. Now closed to vehicular traffic, it formerly carried Crane Brook Road, which now crosses the river on a modern bridge nearby. The bridge is 78 ft and 12 ft wide, and is a single-span Town lattice truss. Built in 1869 by Albert S. Granger, it is the fourth bridge to stand on the site.
