I don’t see how the eastern concourse could be the most congested. It is barely even used for basketball, which compromise most of the events at the Dome.
Still. any improvement is appreciated. Trying to guess where tripling the size of the concourse would put the new exterior wall. There is a row of shoppes/offices/meeting rooms all along the eastern concourse between the concourse and the exterior wall. I am guessing that they will finally recapture that wasted space as part of this. Guessing that would double the size of the concourse. I guess it could triple it but I don’t think so.
So it sounds like the new concourse will probably extend into the area between the stadium and the Barnes Center. Not sure if the new restrooms and food options will cut into the new triple the size concourse. I hope not but suspect this is what will happen. If they add more space along that eastern border for food and rest room options, it would be a lot better. Although if they do that, opening up the area to the sun using glass or ETFE would not make sense, which is unfortunate.
There are no restrooms behind the end zone sections and little in the way of food options. Adding these would be great, but the side that needs them even worse is the western concourse.
