Photo: Antonio F. Futterer, Holyland Exhibition, 1962. The 2 Freeway sliced into that hillside where Corralitas Walk runs down the chain link fence to Corralitas Drive and the Red Car Property. (The 2 Freeway is about 20' below the chain link fence on the right.) Unfortunately, we don't have a good "before" shot to compare it to. (Click on photo to enlarge.)
Also worth noting, CalTrans never saw fit to give us real sidewalks adjacent to the freeways. It's just asphalt with a curb, blocked with telephone poles so you can't even walk down the "sidewalk" without stepping off the curb.
