 SH 103 was originally designated on February 17, 1925 from Centerville east through Crockett to Lufkin, and SH 103 was conditional on location and construction.On March 28, 1927, another SH 103 was created as a renumbering of SH 104 from Ranger to Morton Valley (as it was unsure if the other SH 103 would be built).This SH 103 was eliminated by 1930.
