Notes:

• J.W. Pigg (of Mitchell & Pigg, prominent Texas suspension bridge builders of the early 20th century) was reportedly involved in the construction of the bridge. Steinman gives a date of 1922, but newspaper articles from mid-1923 describe the plans as still under consideration. The bridge was likely completed in 1923 or 1924.
• A photograph of the bridge appears in the December 16, 1934 issue of The Daily Oklahoman (Oklahoma City) with caption: "This Old Bridge Is Doomed," sub-caption "Suspension Bridge on Highway 48 North of Ada," and a blurb: "This old bridge, known as the McKeown bridge, across the Canadian River between Ada and Konawa, is being condemned and will be rebuilt. It is a suspension bridge, one of the few in the state, but when the bridge is rebuilt it will be minus its 'suspenders.'"
• The November 12, 1936 edition of The Ada Evening News reports: "The old suspension, bridge across the river north ot Ada is being torn down, but no one knew just where it will be located when and if it is rebuilt. Konawa wants to build it west of the city of Konawa. Mr. Clark [division engineer for the state highway department] did not know if any provisions have yet been made for its erection."
