State Highway 15 (SH 15) is a state highway in the U.S. state of Texas. It runs from the Oklahoma state line east of Follett to US 54 in Stratford. Route description SH 15 begins at an intersection with US 54 in Stratford. It travels eastward through the far northern reaches of the Texas Panhandle, mainly through farmlands. The route passes through the towns of Spearman and Perryton, before exiting eastward into Northwest Oklahoma, where the road transitions to Oklahoma State Highway 15. History On October 26, 1954, SH 117 was redesignated as SH 15 for its entire route from the Texas/Oklahoma state line in Lipscomb County through the northeast Panhandle to an intersection with U.S. Highway 287 at Claude. The route was renumbered to correspond to the connecting Oklahoma State Highway 15. On September 1, 1965, the section from Spearman southward was redesignated as SH 207, while SH 15 was rerouted westward to Stratford over cancelled routes SH 282 and FM 289. Previous route SH 15 was one of the original twenty five state highways proposed on June 21, 1917, overlaid on top of the Dallas-Louisiana Highway. From 1917 the routing mostly followed present day U.S. Highway 80 from Dallas to Wills Point. It continued on, routed along present day SH 64 from Wills Point into Tyler and up U.S. Highway 271 into Gladewater, and east along US 80 into Longview. On June 17, 1918, the section of SH 15 from Gladewater to Longview was transferred to SH 11. On January 21, 1919, an alternate route of SH 15 was designated east of Wills Point, going through Mineola to Gladewater, via US 80. On November 27, 1922, the section of SH 15 from Wills Point to Tyler was redesignated as SH 15A, which extended to Carthage. The section of SH 15 from Tyler to Gladewater was transferred to an extended SH 31. On August 21, 1923, SH 15A was renumbered as SH 64. On October 26, 1925, SH 15A was designated from Gladewater to Kilgore. On March 19, 1930, this became part of SH 135. On September 18, 1929, another SH 15A was designated along the Scyene Road from SH 15 to SH 14. This highway was erroneously omitted on the March 19, 1930 log, so was unnumbered that day. On November 30, 1932, the former SH 15A was added to the state highway log, but was renumbered as
