Boston area’s ‘Golden Semicircle’

A 1959 issue of Greater Boston Business Magazine contained a two-page map of the region’s “Golden Circle” showing industrial parks and shopping centers springing up along Route 128, which was being completed.

The building of Route 128 created was the nation’s first great high-technology region, fueled by the university complex in and around Boston. It was something of a model for North Carolina’s Research Triangle and what came to be called Silicon Valley in the San Francisco-San Jose area in California.
