This is so broad to be an essentially useless answer, but...demand. Right on that stretch of Post Road, there are vacant storefronts for any smaller businesses (think accountant of insurance agent) to move into rather than buy and build on an empty lot, and it will be better for businesses to be clumped in a plaza like across the street with Kohls, Daves, Marshalls, and soon to be TJMaxx, Starbucks, and Chipotle where someone can park once and hit all of them rather than having to get back on the road to get to the next stop.
