We are in the 200 loop. The noise isn't too bad and our site is fairly close to the 100 loop. There were some cement mixers pouring cement today onto some of the pads which were dug up. Doesn't look like it is changing the size of the pads at all. I just walked over and looked at the site closest to the opening of the loop. New concrete, no change in the shells. So far, we can only see that they are working on 2 pads...could be more, but the loop is totally closed to traffic. My husband thought he overheard the workers commenting about water repair so that may be a part of it.
