Updated 15th July 2025 – The Salt Lake City International Airport is undergoing a transformative 12-year, $5.2-billion redevelopment program to replace its original six-decade-old terminal with a state-of-the-art facility built for future growth. The project’s four overlapping phases have steadily modernized and expanded the airport. The airport boasts one of the longest runways in the USA.

Phase 1, completed in 2020, delivered the new central terminal along with sections of Concourses A and B.

Phase 2 added more gates, completed major parts of the Central Tunnel, and involved demolishing the old terminal—recycling 85% of its materials.

Phase 3, now nearing completion, is delivering the tunnel’s final components, additional gates, and premium amenities, including new Delta and American Express lounges.

Phase 4, scheduled to be finished by 2026, will add 16 more gates, bringing the total gate count to 94 once fully complete.

October 18 2021 – Sterling Construction Company has been granted a US$40.4 million construction contract for the pavement in the Rehabilitation of Salt Lake City International Airport in Utah. The project is part of Design Pack 20 of the Salt Lake City International Airport Terminal Redevelopment Program’s airfield concrete paving package. The Salt Lake City Corporation, through its Department of Airports (SLCDA), launched the Terminal Redevelopment Program (TRP) to welcome more passengers and larger planes while also serving travelers as a hub with enhanced facilities and options.

The US$4.1 billion Rehabilitation of Salt Lake City International Airport in Utah initiative is being developed in stages to guarantee that the project’s Zero Impact to Travelers aim is maintained. Furthermore, the airfield concrete paving package’s Design Pack 20 includes all airfield and civil construction around the North Concourse East. Other significant project components include the Midfield Vehicle Tunnel Ramp and Walls, the destruction of existing taxiways and aprons, the removal of existing utilities, the installation of storm drain, water and sewer, airfield signage and lighting, and communications/electrical duct banks. The project is set to begin construction in February 2022. Once completed, the airport will support 34 million passengers who travel through it each year.

“We are pleased to be a part of the historic New Rehabilitation of Salt Lake City International Airport in Utah project,” said Sterling CEO Joseph Cutillo. RLW has been a significant contribution to this project, and this award demonstrates our capacity to provide value-added services and solutions to our clients. Our strategic transition in our Heavy Civil sector to alternate delivery aircraft projects is progressing well and will be an important element of our strategy going ahead. The New Salt Lake City International Airport project is an excellent example of the sort of environmentally conscious public works projects with which Sterling wants to be identified.”
