History
Construction on the tunnel began in 1849 and was completed in 1852 with the tracks completed in 1853. Work was undertaken by slaves, Irish immigrants, and local workers with Swiss engineers. Three ventilation shafts approximately Шаблон:Convert deep were created during the construction to facilitate air circulation, provide additional work areas, and to enable evacuation of steam and smoke from the steam locomotives during use. The importance of the tunnel was recognized during the American Civil War with both sides fighting over but never destroying the tunnel. The use of the tunnel continues today with freight trains frequently running through it.[1]
