I lack information on who designed and built these shelters, and when. These are the only inverted umbrella park or rest area shelters I have seen (so far).
Notice that these roofs are shaped like an inverted umbrella, with the concrete panels sloping out and up from the center column. This keeps the concrete in compression, unlike the "mushroom" canopies that keep the concrete in tension (see Colby Rest Area Shelters for an example).









This image captures all three of the shelters.
