The idea is that the tunnel could help the building in red here as well as the wing in green become part of the overall retail experience, in addition to “linking” the experience on the east with the experience on the west.
This is why I think the best opportunity for this to happen will be when the North State Bank is redeveloped. When they do that, they will probably be digging down anyway to add a level or two of underground parking. That would be the best opportunity to go ahead and put in a tunnel and build the building to address it. But if they don’t go ahead and do it at that point, then the opportunity is essentially lost.
