Originally constructed in 1972 and opened in 1974, the Conncourse, now renamed the Underground, is a system of tunnels beneath downtown Oklahoma City. It was originally named after banker Jack Conn who conceived the idea along with Donald Kennedy and Dean A. McGee. Construction cost $1.3 million, and it is about a mile long in total.
In 2006, the city finally ended debate by announcing a $2 million renovation, completed in early 2007. The carpet was replaced, the lighting enhanced and the walls repainted. In addition, the plan called for information kiosks to be placed at the entrances with directions and maps.
