SR 251 was established in 1949 along an alignment from its current southern terminus north-northwest and then northwest of the city, to what is now the unincorporated community of Cox.[2][3] In 1955, a short section from Darien to northwest of I-95 was paved.[5][6] By 1963, the road's entire route was paved.[7][8] By 1979, the road was moved to, and paved along its current alignment.[9][10]

The entire route is in McIntosh County.
