Tucson's mayor and council have approved plans for a new $130 million arena and $64 million to expand the TCC in downtown Tucson.

Councilmember Ibarra says it's vital for the public to see tangible results as part of Rio Nuevo's revitalization efforts.

Also in the works: Developers are proposing a 30-story, 712 room Hilton convention hotel next to the TCC, adjacent to Hotel Arizona. If approved, that project could be open to guests in about three years.
