In The Marvelous Mrs. Maisel, S1E4 ("The Disappointment of the Dionne Quintuplets"), Miriam encounters a protest in Washington Square Park led by Jane Jacobs. They're protesting the roads and expressways pushed by Robert Moses (called out by name). There was a proposed extension of 5th Avenue that would have bisected the park.
In the show, there was a poster based on the right side of the diagram here:

No sign, though, so it didn't belong in the other thread.
