Tremont Street Subway

The Tremont Street Subway runs beneath the central business district of Boston, connecting major transportation hubs through multiple underground tunnels and stations.

Construction began in 1895 to create North America's first underground rapid transit tunnel, which opened in 1897 to reduce surface traffic congestion.

The subway construction marked a shift in urban development, encouraging Boston residents to adopt public transportation instead of horse-drawn streetcars.

The tunnel serves multiple Green Line routes through central stations including Park Street, Boylston, and Government Center with connections to other subway lines.

Engineering innovations from its construction influenced the development of subsequent subway systems across North America in the early twentieth century.
