We thought this photo offered some happy insights into the progress of cities. Boston's Big Dig was a massively expensive urban engineering project that put Boston's Central Artery underground, freeing up space on the earth's surface for parks and businesses. The photo above provides the astonishing images of the effect to the city scape that was achieved by putting the artery underground.
It is heartening to see that such salutary effects can be achieved when cities dare impossible feats for the preservation civil life. Although the project met ridicule and falling public support (not to mention falling ceiling tiles) the long term beneficial results seem worth the short term suffering.
