Seaport District build-out (1990s–2010s)
The state extended the Massachusetts Turnpike into South Boston in the 1990s, opening roughly 1,000 acres of industrial waterfront. City and state zoning then guided it into mixed-use development.
The Seaport filled with millions of square feet of office, lab and residential space over two decades.
Established the precedent that South Boston's industrial districts can become dense, high-value neighborhoods.
The same city that transformed the waterfront is now weighing the Dorchester Avenue corridor's industrial-to-residential shift.
