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.
Nodaway River Bridge Nodaway River Bridge is located west of Grant, Iowa, United States. It spans an arm of a small pond in Pilot Grove County Park for 70 ft . The Montgomery County Board of Supervisors accepted a petition from S.M. Smith to build a bridge over the Nodaway River south of Grant in June 1876, and another bridge over the Nishnabotna River at the same time. The county contracted with the Missouri Valley Bridge & Iron Co. of Leavenworth, Kansas to design and build the Nodaway River bridge, which was completed later the same year for $1,000. The bridge consists of a single-span Bowstring arch-truss with a wood deck. It remained in use as a road bridge until 1968 when it was moved to the park for use as a pedestrian bridge. Even though it is no longer in its historic location and used for its historic function, the bridge was listed on the National Register of Historic Places in 1998 as an example of early transportation development in Iowa.
