Hopefully Landrieu genuinely considers tearing down I-10 in New Orleans.
I suppose I'll do this at some point to fill some bloggy space (no time now), but if you're ever a bored nerd like I am look at an overhead shot of a random US city and see where the freeways are. Then imagine the city without the freeways. Then if you dig a bit, try to find a similar shot from 70 years ago.
It's easy to see now how running a massive highway through midtown Manhattan or leveling most of the French Quarter in New Orleans are utterly crazy ideas, but many of the projects that were built were also...utterly crazy ideas which actually happened.
