The 11th Street Bridge was completed in December 1915 to carry vehicles across the Arkansas River at Tulsa, Oklahoma.

[2] 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.

[6] Engineered by Harrington, Howard and Ash of Kansas City, this bridge replaced an earlier wooden structure.

Although it was considered as the centerpiece of a Route 66 exhibit, engineers estimated that it would cost $15 million just to be made safe for pedestrians.

[10] The ability to utilize the existing bridge, rather than having to build another one over the Arkansas, was said to be the major reason U.S. Route 66 was built through Tulsa.

[11] In commemoration of the Route and the man who helped bring it about, the Cyrus Avery Centennial Plaza is located adjacent to the east entrance of the historic Bridge in Tulsa, at the intersection of Southwest Boulevard and Riverside Drive.

[14][c] The plaza features a bronze sculpture, created by artist Robert Summers titled "East Meets West".

The sculpture depicts the Avery family riding west in a Model T Ford auto meeting an eastbound horse-drawn carriage.

Plans include replicas of three neon signs from Tulsa-area motels from the era, being the Will Rogers Motor Court.
