Spur 194 was designated on December 10, 1946 following a longer 2 miles route that began at its present southern terminus at a former stockyard near a railroad crossing and extended further along the present US 385 terminating at what was then US 290 and now Business Interstate 10-G. In 1949, the stretch of the current US 385 south of US 290 was designated as Farm to Market Road 1214 (FM 1214) over a route that eventually was extended to Marathon.
