A former railroad yard, this urban park uses historical artifacts and exhibits to bring to life the controversial and danger-filled construction of the Hoosac Tunnel, one of the greatest engineering feats of the 19th century. The tunnel was dug 4.75 miles through Hoosac Mountain, linking Massachusetts to Albany, NY. 200 men lost their lives building the tunnel, which is still being used today. An audio-visual presentation takes visitors back in time, where the sounds of dripping water, pickaxes against stone, explosions, and debates re-create the hardships and heroism of the tunnel's construction.
