Through frozen ground

In 2002 the Massachusetts BAy Transportation Authority (MBTA) will open a transit corridor less than 3 m (10 ft) below a 100-year-old building in downtown Boston. The mile-long passageway, scheduled for construction in spring 1999, will veer away from the Central Artery Project alignment at the corner of Atlantiv Avenue and Congress Street and pass beneath the Russia Wharf complex and Fort Point Channel on its way to South Boston.
