I’m on a quixotic search for a very specific sort of image, and I thought you might have an idea of where to look. What I’m after is essentially a cross section of downtown Los Angeles, showing structures both above and below ground—e.g., skyscrapers and highways at the top, sewers and subways below. We’ve tried our usual sources on this and come up supremely empty-handed. The city engineers didn’t really have anything either.
This might be unfindable and something we have to commission, but of course I’m hoping to avoid that…. Any tips gratefully received.
