Brewster McCloud (1970) Filming Locations?

I’m a fan of Robert Altman’s 1970 film Brewster McCloud (starring Bud Cort, Sally Kellerman, and Shelley Duvall in her debut acting role) which was filmed in Houston. Most notably at the Astrodome, Houston Zoo, and the former Six Flags. But I’m also curious about the other filming locations such as in the chase scene – photos attached. Is anyone familiar about these (less obvious) filming locations?

P.S. if you’ve never seen this movie it’s extremely wacky but great!
