History
What is now SH-251A was originally added to the state highway system as part of a 1955 extension of SH-16. The highway was paved at this time.
In 1965, SH-16 was realigned to head north from Okay instead of east, and the vacated section of highway was assigned the SH-251A designation.
No changes to SH-251A have occurred since.
In April 2025, the section of SH-251A over the Fort Gibson Dam was closed to traffic due to deterioration of the road deck.
