Last week, we explored how massive engineering projects and car-centric post-war suburbanization transformed the Route 1 corridor over the past 70 years. Now, we’re going to focus on a more-recent phenomenon which has also fundamentally altered the built environment of the Route 1 corridor: urbanism.

You had your office parks, your shopping centers and your residential areas, and never the treble shall meet. But something has changed.
