The Deer Isle Bridge encountered wind stability problems that were similar to a bridge found in which U.S. state?
Tacoma Narrows Bridge (1940) The 1940 Tacoma Narrows Bridge, the first Tacoma Narrows Bridge, was a suspension bridge in the U.S. state of Washington that spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7 of the same year. At the time of its construction (and its destruction), the bridge was the third-longest suspension bridge in the world in terms of main span length, behind the Golden Gate Bridge and the George Washington Bridge.
Indian Fish Trap State Preserve Indian Fish Trap State Preserve, also known as the Indian Fish Weir, is a historic site located near the Amana Colonies in rural Iowa County, Iowa. The fish weir is an array of rocks in a V-shaped formation in the Iowa River. It is the only structure of this kind in Iowa. It is not known when the fish weir was built, possibly in either the Late Prehistoric period or Early Historic period. Glacial boulders from a nearby bluff were probably used to construct it. Each wing of the dam is about 155 ft in length. The fish were thought to be herded toward the vertex of the "V" where they would be easier to net or spear. They were then placed into an adjacent holding pool. Early pioneers discovered the weir, and it was included on a General Land Office map in the 1840s. Archaeologist Charles R. Keyes wrote about the weir in 1925.
