I actually just saw a few of those on StreetView earlier today (they have some fairly recent images dated for 11/21). With the GSV you can kind of make out what it's gonna be like when they are done on both sides of the bridge. And some of the median foundations on the highway EB approaching the bridge from a few miles out - a lot of them are "tagged" as either "OH-[number]" or "G-[number]" (and I believe the numbers ascended/descended oppositely depending on if they were "G" or "OH". It had me curious as to what that indicates.
They also seem to be starting to erect the gantries on either approaching roadway (I saw the foundations for them in the median and on the sides in person last summer on the way to/from the beach).
During my trips to the beach last summer, some of the overhead lane control gantries on the 3-lane span were replaced with monotube structures. The GSV showed a few more have been since then, though not in any real systemic fashion. I wonder if this whole project will have them all replaced on both spans, or if they're just replacing ones that are maybe deteriorating to the point of needing replaced on just an as-needed basis.
