11th Street Bridge

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 Functionally, it has been replaced by the I-244 bridges across the Arkansas. At present, the bridge is in poor structural condition and unsafe even for pedestrians. In 2008, the gates were locked to exclude all visitors. This bridge was added on December 13, 1996, to the National Register of Historic Places under Criteria A and C. Its NRIS number is 96001488. It was named the "Cyrus Avery Route 66 Memorial Bridge in 2004. Although the bridge still stands, it is considered unsafe for use and has been closed to vehicles since 1980 and to pedestrians since 2008.
