A $2 million renovation and enhancement of the three-quarter-mile tunnel system that links 16 blocks and more than 30 buildings in downtown. The original tunnel link was built in 1931 and most the remaining system was developed in the 1970’s and was named after city leader, Jack Conn. The system will be renamed the Underground when the major remodeling is completed. The architectural firm of Elliott Associates developed the renovation plan which includes an exciting lighting plan, new wall colors, a graphics/signage system and new carpet as the main elements of the renovation. In addition, a gallery-style display of historic photographs of Oklahoma City will help inform and educate visitors to downtown.

The project is now complete. The Invited Artists Gallery in the Underground is now open and features the shows created by Oklahoma artists. The Invited Artists Gallery sits underneath the intersection of Robinson and Robert S. Kerr with entrances from all adjacent buildings. The exhibitions are free and open to the public.

The Underground is open Monday - Friday from 6 a.m. - 8 p.m.
