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.
Fort Steuben Bridge The Fort Steuben Bridge, originally the Weirton-Steubenville Bridge, was a suspension bridge which spanned the Ohio River from Steubenville, Ohio to Weirton, West Virginia and carried U.S. Route 22 and then Ohio State Route 822 during its existence. Completed in 1928 and opened as a toll bridge, the Fort Steuben Bridge was a more direct route for the flow of traffic across the river; particularly for trucks and heavy vehicles from the industrial area. The Fort Steuben Bridge was weight-restricted in 2006 and closed in 2009 due to deterioration. The bridge was demolished by Joseph B. Fay Co. on February 21, 2012.
