Hartsfield-Jackson Atlanta International Airport is gearing up for a serious makeover on Concourse C, with a $26.8 million plan to tear into several gates and rebuild key pieces of the operation. The project will overhaul apron-level ground support and gate areas to replace aging infrastructure and give airlines more flexibility in how they use the space. It is one piece of a broader push at ATL to refresh its concourses and better handle a mix of regional jets and larger aircraft.
According to the Atlanta Business Chronicle, the Concourse C work carries an estimated $26.8 million price tag and centers on converting existing gate infrastructure inside the domestic concourse. The outlet reports that recently posted procurement and project documents lay out the scope and signal that the airport wants to move quickly from planning into picking a contractor.
Scope and schedule
Project details from NSS JV describe roughly 50,000 square feet of modifications to ground support and gate areas, with construction expected to start in late 2025 and wrap by summer 2026. The contractor listing ties the effort to the airport’s on-call CMAR program and notes outreach and a bid date that took place last August. That tight timeline suggests airport planners want to keep the most disruptive construction period as short as they reasonably can.
Part of a wider rebuild
The Concourse C conversion lands in the middle of a years-long slate of upgrades at ATL, including the modular widening of Concourse D that is designed to boost gate capacity and passenger space, as reported by the Atlanta Journal-Constitution. Engineering teams on that project have leaned on off-site modular construction and careful phasing so much of the concourse can keep operating while major work is underway. As WSP notes, that approach has allowed ATL to add substantial new gate space without shutting the whole concourse down.
What travelers might notice
For passengers, the Concourse C project will likely look like the usual airport construction routine: temporary walls, extra signage and the occasional scramble to a newly reassigned gate while crews work on apron and gate systems. The airport has leaned on phased construction in recent projects to avoid long stretches of gate closures, a strategy outlined by ATL Next. Anyone flying through Concourse C during the construction window will want to keep an eye on airline apps and airport alerts for short-term changes.
Next steps
Procurement notices and contractor listings point to active outreach and bid efforts tied to the Concourse C conversion, with final timing still dependent on airline coordination and operational approvals. That activity is reflected in project postings by NSS JV. If the current schedule holds, construction crews could be on site by late 2025, with an initial completion target around mid-2026.
Bottom line
The Concourse C gate conversion is a focused, mid-sized piece of the larger ATLNext capital program, aimed at modernizing gates while keeping the airport’s hub operations humming. As contracting and phasing plans are finalized, the airport and its partner airlines are expected to release more detailed gate-closure and construction timelines. In the meantime, travelers can expect a bit of near-term inconvenience in exchange for updated gates and a smoother operation down the line, so it is worth watching airport and carrier notices as the work takes shape.
