Texas State Highway 2

The route had numerous spurs and alternate routings during its lifetime.

Historic SH 2A

For the initial June 21, 1917 Texas routing proposal, while the main route continued southwest from Cleburne to Meridian, and then southeast to Waco, State Highway 2A ran southeast from Cleburne to Hillsboro, where it met State Highway 6.[7] On April 23, 1918, the routing of SH 2A remained similar, except the split from the main route happened at Burleson, travelling southeast through Alvarado to Hillsboro.[8] On August 21, 1923, the main route of SH 2 had been rerouted over SH 2A section from Burleson to Itasca, while SH 2A was reassigned to the old alignment of SH 2 from Burleson to Cleburne and to the old alignment of SH 2E to Hillsboro. The old route of SH 2 was renumbered as SH 89 (now SH 174) from Cleburne to Meridian and part of SH 67 (now SH 6) from Meridian to Waco.[9] The SH 2A designation was deleted on September 26, 1939 and was replaced by portions of SH 174, SH 171, and SH 291 (now FM 2719).

Historic SH 2B

State Highway 2B was a spur designated on December 18, 1917, in McLennan County running from Riesel northeast to Mart along an already constructed section of what was previously proposed as part of SH 7. On March 20, 1922, SH 2B extended to the Limestone county line.[10] On December 17, 1923, it was cancelled.[11] SH 2B was designated that same day over a former routing of SH 2 from Round Rock east and north to Temple via Taylor. On April 6, 1932, it was transferred to SH 95 and SH 43 (now US 79).[12]

Historic SH 2C

A more direct route through central Texas between Belton and Round Rock, bypassing Taylor to the west designated as an intercounty highway on January 24, 1918.[13] On July 17, 1918, this was upgraded to a state highway, State Highway 2C, and extended north to Temple.[14] On December 17, 1923, the main route of SH 2 had been rerouted over it.

Historic SH 2D

State Highway 2D was a spur route in north Texas designated on December 16, 1918 branching off the main route at Bowie and travelling north through Ringgold and crossing into Oklahoma.[15] On August 21, 1923, the main route of SH 2 had been rerouted over it, with the old route of SH 2 transferred to SH 50 (now US 287), SH 5 (now US 287), and SH 30 (now US 277).[9]

Historic SH 2E

State Highway 2E was a short connector route between Cleburne and Itasca designated on March 22, 1921, connecting the main route and SH 2A.[16] On August 21, 1923, SH 2E was reassigned to SH 2A.[9]

Historic SH 2F

State Highway 2F was a planned spur routing designated in 1921 or 1922 splitting from the main route in Taylor and travelling south to Elgin. On August 21, 1923, the route was cancelled,[9][17] and on April 21, 1924 the route was restored as SH 95.[18] A new SH 2F was designated on March 18, 1929, from Bowie to Montague.[19] On April 23, 1929, it extended north to Nocona.[20] On March 19, 1930, SH 2F was renumbered as SH 59.
