SAT Begins Curbside Construction for New Terminal C Expansion

San Antonio International Airport (SAT) is initiating the first major phase of curbside construction on March 23, 2026, marking a significant public-facing step in its ambitious $2.5 billion Elevate/SAT capital improvement program. The work, which will reconfigure traffic lanes at Terminals A and B, is expected to cause intermittent traffic delays for passengers over the next two years but is critical for the development of a new, modern Terminal C.

The initial construction phase is a key component of the airport's broader Terminal Development Program (TDP), a 20-year master plan designed to accommodate record passenger growth seen in 2023 and 2024. This first stage, scheduled for completion in December 2026, will directly support the construction of the new Terminal C, a facility projected to add up to 17 new gates and over 850,000 square feet of space. According to the City of San Antonio, the overall project is expected to generate a $2.8 billion economic impact and create 16,000 jobs for the region.

Airport officials acknowledge the potential for disruption. Jesus Saenz, Director of Airports, advised travelers to "pack a little bit of patience," while noting the project's goal is to simplify airport entry and departure in the long term. The construction will impact local passengers and drivers, who will face lane closures and reduced curbside space, potentially requiring the use of short-term parking for drop-offs. Rideshare and shuttle operators will also be affected, as pick-up and drop-off locations are being shifted to manage commercial traffic flow.

Project Scope and Funding

The Elevate/SAT program is backed by significant federal funding. The Federal Aviation Administration (FAA) awarded SAT a $13.3 million Airport Infrastructure Grant in July 2025, made possible by the Infrastructure Investment and Jobs Act (IIJA). This grant specifically targets mass excavation, drilled piers, and utility work essential for the new terminal. Further details on the project's scope and passenger advisories can be found on the airport's official construction update page.

The expansion at SAT reflects a wider industry trend of mid-sized U.S. airports undertaking massive capital improvements to handle post-pandemic population growth and the airline industry's shift toward larger aircraft. The comprehensive plan aims to increase the airport's total gate count to approximately 40, positioning it for future domestic and international growth.

This type of large-scale redevelopment while maintaining full operations presents significant logistical challenges. In 2016, LaGuardia Airport's (LGA) $8 billion rebuild resulted in a modern, unified terminal but caused severe initial traffic congestion—a pattern that SAT aims to manage through phased construction and clear communication. Similarly, Salt Lake City International Airport's (SLC) $5.1 billion redevelopment, completed in 2024, demonstrates the industry-wide move to replace aging infrastructure to meet modern aviation demands.

Technical Analysis

The SAT expansion is more than a capacity upgrade; it represents a strategic investment driven by regional economic and demographic shifts in Central Texas. The project's design, which includes a future Ground Transportation Center (GTC) to centralize access for taxis, rideshares, and public transit, indicates a forward-looking approach to mitigating the curbside congestion that plagues many growing airports. This development follows the trajectory set by hubs like LGA and SLC, confirming that multi-billion-dollar infrastructure renewals are becoming standard for airports transitioning from regional spokes to significant connecting hubs. The reliance on federal funding through the IIJA also highlights a national strategy to modernize critical aviation infrastructure to support economic competitiveness.

What Comes Next

According to airport leadership, the massive project remains on track. Tim O'Krongley, Deputy Aviation Director, confirmed in February 2026 that the Terminal C project is "on time, on schedule, and on budget." Following the completion of the first curbside construction phase, several other milestones are planned.

Key predictive milestones for the Elevate/SAT Terminal Development program include:

• Phase I Curbside Construction Completion: December 2026 (confirmed by San Antonio Airport System)
• New Parking Garage and GTC Construction Start: Late 2026 (expected)
• Terminal C Grand Opening: Mid-2028 (confirmed by City of San Antonio Aviation Department)

Why This Matters

The San Antonio International Airport expansion serves as a key example of how mid-sized airports are adapting to become primary economic drivers for their regions. For airlines, the addition of 17 gates creates significant opportunities for new routes and increased frequencies in a high-growth market. For passengers and the local community, the project promises long-term improvements in efficiency and amenities at the cost of short-term construction-related inconveniences.
