Route description
SH 102 begins where NM 421, an 8.1-mile (13.0 km) route approaching from NM 402 between Clayton, New Mexico and Amistad, New Mexico, crosses the state line near Sedan.[2] SH 102 intersects FM 296 to Texline just east of the state line. The highway has a short concurrency with FM 3110 before terminating at US 87 7.0 miles (11.3 km) northwest of Dalhart.[1][3]
The 27.7-mile (44.6 km)[4] rural highway passes through no cities or towns and intersects no major highways between its termini. SH 102 travels in a straight line for almost its entire length encountering only flat High Plains terrain.[5][6]
History
SH 102 was originally designated on February 17, 1925, from Claude to Panhandle.[7] On May 4, 1925, SH 102 was also designated over a route from Taylor via Lexington to Caldwell in Williamson, Milam, Lee, and Burleson counties.[8][9] On March 18, 1927, the route from Claude to Panhandle was renumbered as part of a new SH 117, leaving only one SH 102 from Taylor via Lexington to Caldwell. On October 20, 1931, SH 102 was cancelled.[10] On March 2, 1932, SH 102 was restored from Taylor to Lexington only.[11][12][13] This route was renamed FM 112 on October 24, 1944.[1][14]
The current highway was first designated as Farm to Market Road 808 from the eastern terminus at US 87 to a point 13.3 miles (21.4 km) westward on July 20, 1948, along with FM 807 in the same county.[15] The road was extended to the New Mexico state line on December 16, 1948.[15] During the 1950s, NM 102 was extended eastward from Sedan to the state line meeting FM 808.[16][unreliable source] On March 30, 1955, the Texas highway department began signing the road as SH 102 in conformance at that time with the New Mexico numbering, but the road officially retained its FM 808 designation.[1] The portion of NM 102 approaching the state line was renumbered NM 421 in 1988.[16][17][unreliable source] The road officially achieved its SH 102 designation on August 29, 1990,[1] and the FM 808 designation was decommissioned.[15]
