Gate Expansion Program

Gate Expansion C-East Construction

New Concourse C East opened May 5, 2022

Over the last 27 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. 

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.

Gate Expansion: budgeted $1.5 billion

This program is funded through airport revenue bonds, not taxpayer dollars.


The DEN Gate Expansion Program broke ground in 2018. All expansion areas are expected to be operational in 2022.
