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.
Adel Bridge The Adel Bridge is located on the east edge of Adel, Iowa, United States. The 400 ft span carried traffic on River Street over the Raccoon River. The Dallas County Board of Supervisors received a petition to replace a deteriorating bridge at this location. The old bridge had been built where ferry service had been initiated in 1850, three years after the town had been established. They contracted with the King Iron Bridge and Manufacturing of Cleveland to build the two-span Pratt through truss bridge for $12,500. It was a primary river crossing into Adel until 1932 when the U.S. Highway 6 bridge was completed not far to the south. While it remains in place, it was closed to vehicular traffic in 2000. The bridge was listed on the National Register of Historic Places in 2002.
