Man, that would have been a rather impressive addition had they completed it. Unfortunately, given the trend of big box department stores as well as the demise of Kaufmann's, I think this thing would have struggled somewhat. However, given the fact that it would have had direct access to Steel Plaza Subway Station, pretty much making that into a hub of sorts on the T, it probably would have faired much better, than, say the Allegheny Center retail complex. I wonder why this fell through... I'm guessing they could not secure tenants for the other buildings or any of the remaining retail space. Given today's market, I'd see this as a rather tough sell still, especially given big box retail.
I always thought Steel Plaza seemed "unfinished," and now I know why that was...
