Oh, you'd be nervous all the time driving in Boston! With histroically huge in every way imaginable The Big Dig, you're either driving far above the city, or below it - which means under Boston Harbor for parts of it, and every one of the tunnels is below sea-level. Only one person has been killed by a tunnel collapse, but many people get worried driving through it.

Me, I just go blissfully through, thinking "cool tunnel!" Or "pretty bridge!" After having the entire city under detours, destruction and construction for seemingly ever, it's nice to drive on the results! Not, mind you, that it's complete or anything, but parts of it are drivable.
