Denver International Airport officially broke ground on the three-and-a-half year renovation of its terminal this summer, an area known as the Great Hall. That is the area under the tent roofs of the terminal, which encompasses nearly 1.5 million sq ft. The project will make substantial improvements to Levels 5 and 6 of the terminal. The Great Hall Project is expected to create 400 to 450 construction jobs, more than 800 new permanent jobs and generate an additional $3.5 million in annual taxes. The project is intended to enhance security, provide a more flexible and open airline check-in space and add new dining and shopping options. It will also increase capacity of the terminal, update the aging facility and improve the overall passenger experience at DIA.
