This is exactly what's happened here in Boston after the Big Dig was finished--traffic is still bad. Now, there were some advantages--no one misses the elevated southeast expressway--but the roads around here are often still jammed. A similar process happens with housing too--as more is made available, people want more of it, which contributes to there never being enough, no matter how much you build.
