Named for Frank P. Sebree (1854-1940), a Kansas City attorney who server in many public roles including as a member of the Park Board and as a judge. Sebree descendants still practice law in Kansas City.
Benton Boulevard was part of Kansas City's system of parks and boulevards built around a century ago. Just south of this bridge it intersects Swope Parkway, another boulevard.
