SOUTH SHORE PLAZA was enclosed and climate-controlled in 1976-1977. Between 1978 and 1980, the mall was expanded toward the south and north (shown in shades of gray). Lord & Taylor and Sears joined the retail roster and a north parking garage was built.
A circa-1996 layout. The mall had just been expanded with an Upper Level of stores and services. A second parking garage was built and Jordan Marsh was "Macy-ated". As a footnote; in the early '90s, the section of Massachusetts Route 128, adjacent to the north side of the complex, had been redesignated as Interstate 93 / US 1.
