 Oklahoma City Underground

The Oklahoma City Underground is a series of pedestrian tunnels and skyways connecting skyscrapers, hotels and venues in sections of Downtown Oklahoma City's central business district.The original tunnel was dug in the early 1930s because William Balser Skirvin wanted to have an underground passage from his "Skirvin Hotel" on one side of Broadway to his new hotel, The Skirvin Towers, on the other side of Broadway.
