I can tell you why they recess the highways in the inter city like that. Contrary to popular belief it's not so thugs can throw rocks or take pot shots at you while you are driving by. It's a natural sound baffle. Paul
The new High School of the Arts in downtown Los Angeles. To the left is the relatively new, as cathedrals go, Our Lady of the Angels. Though I have lived here for decades and decades I don't think until this image, shot from the top of a parking structure, I quite understood that the main part of the main freeway through Los Angeles was, as in many cities, in practical effect, underground.
What is that structure in the upper right corner with right angle triangle base, rectangle box on top the spiral something wrapping around it? Also curious about your vantage point here, you appear to be over the hwy. PA
