All of the gates are expected be operational by spring 2021.

The $1.5 billion Gate Expansion Project is being managed by two joint-ventures: Holder Construction and FCI Constructors Inc. on Concourse B-East and Concourse C-East, and Turner Construction and Flatiron Construction on Concourse A-West and Concourse B-West. HNTB Corp. and Jacobs Engineering Group will provide architectural and design services for the project.

Since 2011, the airport has added 11 new airlines, 13 new international destinations and 28 new domestic destinations.

The Denver airport opened in 1995 and currently has 107 gates with 42 apron load positions. The three concourses are configured as follows:

  • A Gates: 1,900 feet (579 meters) long, 1,220,000 square feet (113,342 square meters)
  • B Gates: 3,300 feet (1,006 meters) long, 2,033,872 square feet (188,953 square meters)
  • C Gates: 1,900 feet (579 meters), 789,000 square feet (73,301 square meters)

In 2014, the airport completed work on five new gates on the C Concourse. The $46 million expansion added 39,000 square feet of space to the west end of the concourse. All of the gates are currently occupied by Southwest Airlines.

In the current expansion project, the airport’s A concourse will add 12 gates, its B concourse 11 gates and its C concourse 16 gates.

The new gates are one of several projects in the airport’s $3.5 billion, five-year capital improvement program.
