History of the T
Boston was the first city in the United States to build a subway. The first tunnel opened in 1897 between Haymarket and Boylston - today's Green Line. There was a fury of rapid transit building in the early 1900's: the Orange Line from Sullivan Square to Dudley Square opened in 1901, the Blue Line from State Street to Maverick opened in 1904, and the Red Line from Harvard to Park Street opened in 1912.
Boston’s transit network continued to expand in the 1910’s and 1920’s with development coming to a halt in 1932. In 1954 and 1959, the Blue Line was extended and the Green D Line opened. T expansion resumed in the 1970's and 1980's.
However, since 1985, there has been no rapid transit expansion in Boston - a 30 year drought that we need to recover from right away.
