Boston may own New York in baseball, but in regards to creative re-development of disused behemoths of the mid-20th century, they may be woefully behind Gotham. Consider Sunday's Times article  describing the slow evolution of the park being built atop the Big Dig where Boston's old Southeast Expressway used to run.
"Jerold Kayden, a professor of urban planning and design at Harvard, said that the parks lacked boldness and creativity and that the corridor remained an urban void. It might have been more interesting, Professor Kayden said, to leave the highway intact as an elevated park like the planned High Line, formerly a railway, on the West Side of Manhattan."
