Transit stop · 1912

The Red Line

The MBTA subway line that strings Cambridge together — Alewife through Harvard, Central, and Kendall to downtown Boston. Opened to Harvard in 1912, it is the spine the city’s densest knowledge and innovation districts grew along.

Why it matters

No single piece of infrastructure shaped modern Cambridge more — Harvard, MIT, and Kendall all organize around its stops.

Why these are connectedThe Red Line Kendall Square

Kendall’s biotech boom is inseparable from the Red Line: the line delivered the workforce that the district’s labs and startups run on, and every major employer clustered within walking distance of the stop.

Evidence
  • Kendall/MIT station sits at the district’s center
  • Firms explicitly recruit on transit access
  • Density of development falls off sharply away from the line

  • MBTA
