This actually depicts two WYDOT rest stops, the two probably being the two busiest in the state. They're on a long stretch of Interstate 80. Offhand, I think these are the first rest stops, going west, since the one at Ft. Fred Steele.
That's a long ways.
This is two, not one, rest stops, as the highway is divided. The two rest stops are likely 1/4 mile distant from each other, on opposite sides of the highway.
They aren't in a scenic location, which no doubt is besides the point. Dedicated to the Dwight D. Eisenhower Highway, they're on part of the path of the old Lincoln Highway and near the Union Pacific Railroad's location. In some ways, they're the closest thing a modern traveler will experience to the old stage stop. No food, of course, but a place to briefly stop in the middle, more or less, of Wyoming's Red Desert.
Indeed, on the day I took these photos, a traveler from out of state was taking his horses out of his horse trailer for a break.
