Over the last 26 years, Denver International Airport has grown from 33.1 million annual passengers to more than 69 million passengers. While passenger traffic slowed in 2020 and 2021 due to COVID-19, DEN has outgrown its facilities which were built for 50 million passengers. In response, DEN is making many improvements to accommodate the continued growth, including expanding and enhancing Concourse A-West, Concourse B-West and B-East, and Concourse C-East. This work also includes renewal to the existing infrastructure in each concourse. 

Phase 1: Gate Expansion 

DEN is building 39 new concourse gates, increasing overall capacity at the airport by 30%. The new gates will be added on all three concourses to allow DEN’s airlines an opportunity to grow and for DEN to accommodate new airlines, including international carriers. In May of 2018, DEN broke ground on Phase 1 of The Gate Expansion Program and opened the first completed area, B-West in November 2020.  More information about Phase 1 is available here. 

Phase 2: Concourse Renewal

On May 18, 2020, DEN went before Denver City Council to request an amendment to the current program contract. DEN was approved for a $560 million-dollar contract amendment to update and renew existing facilities. The concourse renewal work was added to the program to allow DEN to make necessary improvements to aging airport facilities and spaces while passenger traffic is low due to COVID-19. Renewal work for Phase 2 of this program with the additional funding approved by city council will begin in 2021.

Total Program Costs:

Expansion Phase 1: $ 1.5 billion

Renewal Phase 2: $560 million

The Gate Expansion and Concourse Renewal Program is part of DEN’s $3.5 billion Capital Improvement Program (CIP), which is funded through airport bonds. In 2018, DEN issued approximately $2.1 billion in bonds to fund the CIP. These funds are dedicated specifically to CIP projects and cannot be used for operations and maintenance of the airport. 


The DEN Gate Expansion Program broke ground in 2018. All expansion areas are expected to be operational in 2022. Phase 2, Concourse Renewal is scheduled to be complete in 2024.
