Demolition appears to be underway for the planned "Topgolf" facility. I believe this is to be roughly bounded by Engel Street, Gisholt Drive, S Towne Drive, W Broadway, and WPS Drive. However, some streets may be reoriented or removed in favor of parking lots.

Exchange Street was recently rebuilt, with bike lanes, on-street parking. Needs to be updated
