As ranchers and merchants settled in this part of Texas during the 1870s, the need for a direct supply line became evident. This trail was established in 1877 for cattle drives and freight hauls from Tascosa (38 mi. SW) to markets in Dodge City, Kansas. It also served as a stagecoach and mail route. The town of Tascosa received a post office in 1878 and was the Oldham County seat from 1880 until 1915. The coming of the railroad in 1887 led to the decline of the town and to the abandonment of the Tascosa-Dodge City Trail. (1966)
