Looking at a Google Earth overhead view of that location, it might even be possible to leave the Thruway where it is if the area between Illinois and Michigan Avenues could be acquired and extended from South Park to Scott Street. Seems like a big enough parcel with even room for some parking, similar to Raven's Stadium.
