SH-99 continues as K-99 after crossing the border into Kansas. This road continues for 233 miles (375 km) to the Nebraska border, where it becomes Nebraska Highway 99, which lasts an additional 14 miles (23 km). Thus, SH-99 is part of a triple-state highway numbered "99", which lasts a total of 488 miles (785 km).
SH-99 began as SH-48, a short highway connecting Ada to Holdenville. This highway was gradually expanded until it became a border-to-border route. In 1938, it was renumbered to match K-99, which was renumbered from K-11 the same day.
