 By June 1930, the northern terminus of SR 35 was truncated to Moultrie, replaced by an extension of SR 33, which eliminated its split.In the first quarter of 1937, the entire length of SR 33 that existed at the time had a "completed hard surface".In the third quarter of 1939, SR 133 was extended on SR 35 south of Moultrie, south-southeast to SR 122 in Pavo, and south-southwest to US 84/SR 38 in Boston.
