State, well known as State Street, is a subway station of the Massachusetts Bay Transportation Authority. Located in downtown Boston, Massachusetts, USA, State is the transfer point between the Orange Line and the Blue Line, as one of the quartet of "hub stations" on the MBTA subway system.What later became the Blue Line platforms of State station were opened in 1904, making it the oldest surviving MBTA rapid transit (heavy rail) station. (The Tremont Street Subway, opened in 1897, serves only Green Line (light rail) streetcars). After an extensive renovation which was completed in 2011, State is fully handicapped accessible.HistoryEast Boston TunnelThe Blue Line section of the station was built along with the rest of the East Boston Tunnel in the first years of the 20th century and opened on December 30, 1904, serving streetcars running from downtown to East Boston. An unusual aspect of State Street station is the entrance built directly into one of Boston's best-known historic sites, the Old Massachusetts State House. This entrance often confuses first-time tourists and visitors with its unconventional location. The East Boston Tunnel station was originally known as Devonshire after the street which the Old State House is located on. The station is the only remaining station on the tunnel opened in 1904.
