I-81 is a monstrosity that will cost at least as much to upgrade to a 21st-century highway at it will to tear it down. Guess which neighborhoods it destroyed? Yep, it was those neighborhoods already doomed by official redlining in the 1930's. (See http://syracusethenandnow.org/Redlining/HOLC_Maps.htm) If we were to put a real boulevard through, though, their property values should skyrocket.
