Unfortunately, that was the outcome of all but 41 of the 674 roadside parks built by the NYA. Nine of the remaining 41 are in Jeff Davis county, near Ft. Davis in far west Texas. Lyndon Baines Johnson was the first director of the Texas branch of the NYA from 1935-37, during which time the first 200 of the parks were constructed in anticipation of the tourists to Texas for the 1936 Centennial Celebration.
...to provide cool shade alongside tortuous highways navigated by Depression-era cars without air conditioning. (Barnes, 2011)While "tortuous highways" seems a bit of an exaggeration, certainly there were parts of Texas that did have long stretches of highway and in the hot summers, a roadside park was a welcome pit stop for a bit of shade and rest. During the Depression, as well as later, travelers would pack picnic lunches and cool drinks in an ice chest for those rest stops. Many had stiles to allow a traveler to cross the fence for a literal "pit stop" in a neighboring field or pasture. While that might seem odd now, there were no convenience stores, McDonald's, or other readily available alternatives for either food or restroom options. Many of the few stations available prohibited non-paying customers from using restrooms, and they were certainly not present along rural stretches of road.
