This is more a "ballpark activity" update than a construction update.
BCB's David Sameshima was at Wrigley Field both Tuesday and Wednesday and didn't find too much construction activity, but did find some other interesting things happening around the ballpark:
I had to meet someone at the ballpark before the game Tuesday, but wasn't going to the game. I did take a few photos of the plaza building. Quite a bit of the structure is now up at the corner of Waveland and Clark. There is a new sign over by the broadcast center lot on Waveland.
