What about removing the Pierce and routing all traffic along the east side of downtown on a widened 59? From a land aquisition standpoint, all you have to do is buy all the blocks between Chartres and St. Emanuel and have a super wide/double deck/sunken freeway to handle the throughput. Much cheaper than trying to buy high-rises and you could probably make a few bucks selling the half blocks along where the Pierce is now. Just my $0.02
