Every large American city has a dedicated manufacturing and industrial district that was created from scratch in the late 1950s and 1960s to remove industry from the central business districts and to relocate manufacturing companies to the new interstate highway system. Many of the districts, such as Newmarket in Boston, Mill River in New Haven, CT, and Morris Point in the Bronx, still have vital companies, but not at the density that they had at their inception and through the 1970s. The question today is what to do with these districts from an economic development and urban design standpoint.
