Officially designated on August 24, 1924, the original route encompassed all of current SH-9 west of Blanchard. East of Blanchard, SH-9 followed a more northerly route. Bypassing Norman, SH-9 ran north to Oklahoma City before going east through Harrah, Meeker, Prague, Henryetta, and Checotah. The highway ended at the original State Highway 3 in Spiro. Upon the creation of the United States Numbered Routes system in 1926, the section between Oklahoma City and Warner was overlaid with U.S. Highway 266. Four years later in 1930, SH-9 was truncated to Chickasha. By this time, much of the route had become part of U.S. Highway 62.
