'''State Highway 102''' ('''SH 102''') is a state highway in the U.S. state of Texas maintained by the Texas Department of Transportation (TxDOT). The highway begins at the New Mexico state line near Sedan, New Mexico as a continuation of New Mexico State Road 421 ending at U.S. Route 87 near Dalhart. SH 102 is located in southwestern and south central Dallam County and does not pass through any cities or towns. The highway was first designated in 1948 as a Farm to Market Road before eventually being upgraded to its current highway designation.
