Parking and also other infrastructure, mainly highways and larger roads that cut up the city. The largest benefactors of the Big Dig in Boston (http://en.wikipedia.org/wiki/Big_Dig http://en.wikipedia.org/wiki/Big_Dig) were not those driving on the newly improved road or those benefiting from the reduced traffic, but rather those who could now enjoy the green way, those living in or visiting the North End (hey I can walk there now!), those benefiting from the improved air quality of having a filtered highway, etc.
