Photo of the Minhocão elevated expressway in central São Paulo, built in the 1970s to relieve congestion but only uncongested itself on Sundays, when it’s closed for traffic and becomes a sort of public park. Here’s a video of what it looks like on weekdays. I’d heard that the name just meant “big worm” in Portuguese, but it turns out there’s a whole bigfoot-type legend of a truly giant minhocão tunneling somewhere in the jungles of South America. The photographer is originally from Mexico and has worked extensively there and in Europe and Brazil.
