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.
I-5 Skagit River Bridge collapse The I-5 Skagit River Bridge collapse occurred on May 23, 2013, in the state of Washington, in the northwestern United States. At approximately 7:00 pm PDT, one bridge span carrying Interstate 5 over the Skagit River collapsed into the river below. Three people in two different vehicles fell with the span; they were rescued by boat and did not sustain serious injury. The cause of the collapse was determined to be an oversize load striking several overhead support beams on the bridge, which led to an immediate collapse of the northernmost span.
