Browsing Google Maps today I noticed that the imagery had changed above Detroit. This must have happened in the last few days- I hadn't noticed it when I checked it last Tuesday. It looks fairly recent- perhaps in the last few months, even weeks. Some things to note:

-Brewster Douglass Completely Demolished
-Capitol Park is finished
-Lafayette Greens is finished
-Woodward torn up for M1 Rail Construction
-Fort Street Bridge out

Also, can someone tell me what the orange-and-white barriers are doing along Woodward, Grisworld, Washington, and Jefferson? Thanks.
