Great write up. It's always interesting hearing about how these freeways got built. This freeway has two of my favorite interchanges, The Judge interchange and 101/110 four level. I've always been intrigued. *if* they ever decide to replace that one day I would love to see it deconstructed in segments and preserved somewhere.
There's a project to improve the express lanes by extending(I'm being very generous with that word) them to terminate directly into Adams Ave with two alternatives one being a new bridge.
