11th Street Bridge - Credit: Wikimedia Commons
The 11th Street Bridge was completed in December 1915 to carry vehicles across the Arkansas River at Tulsa, Oklahoma. Used from 1916 to 1972, it was also a part of U.S. Route 66. Functionally, it has been replaced by the I-244 bridges across the Arkansas. As of 2009, the bridge was in poor structural condition and unsafe even for pedestrians. In 2008, the gates were locked to exclude all visitors.Bryan, Emory (May 14, 2009). "Historic Tulsa Bridge To Remain Closed". Read more on Wikipedia
