The Hoosac Tunnel (also called Hoosic or Hoosick Tunnel) is a 4.75-mile-long (7.64 km) railroad tunnel in western Massachusetts which passes through the Hoosac Range, an extension of Vermont's Green Mountains. Work began in 1848 and was finally completed in 1875. At the time of completion, it was the second longest tunnel in the world (after the 8.5-mile-long (13.7 km) Mont Cenis Tunnel through the French Alps). It was the longest tunnel in North America until the completion of the Moffat Tunnel in 1928, and remains the longest active transportation tunnel east of the Rocky Mountains. Electric locomotives were used from 1910 to 1946 to reduce smoke problems. The tunnel's east portal is along the Deerfield River in Florida, Massachusetts (424031N 725953W / 42.675163N 72.997938W / 42.675163; -72.997938). The tunnel runs in a straight line to its west portal in North Adams, Massachusetts (424032N 730529W / 42.675447N 73.091376W / 42.675447; -73.091376.

The garage door on the west portal is a part of the ventilation system.
