Boston, Massachusetts, was home to the first subway system in North America, opened in 1897.

Quick answer

  • The first subway system in North America was the Tremont Street Subway in Boston.
  • It opened to public service on September 1, 1897, as an underground streetcar tunnel to relieve downtown traffic.
  • This Boston subway became the prototype for later U.S. systems, including New York’s, which opened its first major line in 1904.

A tiny bit of story

In the 1890s, Boston’s downtown streets were so clogged with horse-drawn vehicles and streetcars that the city decided to move part of its transit network underground. Construction began in 1895, and when the Tremont Street Subway opened in 1897, more than 100,000 people rode it on the first day, signaling a new era of urban transportation. Within a few years, other cities followed—most famously New York City—but Boston holds the historical “first subway in North America” title.
