Lincoln Institute and Harvard Loeb Fellow Peter Park gives a presentation on what's after the freeway brings growth!(somewhere else)! American city. Here is the link, the embedding is disabled, which annoys to no end.
And when you're done with that, go ahead and flip through my presentation on IH-345 tear-out which is actually market-oriented, will bring growth back towards the city, and generates public (and private) good. But it also can't embed. ARGH!
