San Antonio International Airport (SAT) is preparing for a significant infrastructure upgrade that will temporarily alter traffic flow for passengers. According to an official press release from the City of San Antonio Aviation Department, the airport will commence construction on its terminal curbside lanes as part of the broader Terminal Development Project.
We note that this initiative, falling under the ELEVATE/SAT program, aims to expand the airport’s capacity to accommodate future regional growth. The upcoming work represents a critical step in modernizing the facility and preparing for the addition of a new terminal.
Beginning on March 23, 2026, the airport will initiate the first phase of a multi-phase lane closure plan. The city’s press release indicates that two of the four lanes located at the far end of Terminal B’s upper and lower levels will be closed. This closure is necessary to facilitate roadway modifications that will eventually support the planned Terminal C.
A major focus of Phase I is the construction of a zero-curb transition connecting the existing roadway to the future Terminal C. Airport officials highlighted in the release that this design prioritizes accessibility, creating a seamless, barrier-free path from the street directly into the terminal. Additionally, crews will begin erecting the Terminal C canopy, which is designed to offer weather protection and enhance the overall curbside experience once finalized.
“This next phase of SAT’s transformation represents far more than infrastructure. For millions of travelers each year, SAT is the first and last impression of our city and today is a next step in building an experience that reflects the energy and hospitality of San Antonio. All passengers deserve an airport experience that is accessible and free from barriers.”
With the lane closures imminent, travelers and drivers should anticipate temporary shifts in how they navigate the terminal roadways. To mitigate congestion and ensure a smooth experience, the airport is advising passengers to arrive early.
The aviation department’s release outlines several alternatives to traditional curbside pick-up and drop-off. The Short-Term Parking Garage provides dedicated three-hour spaces, costing $5 for the initial hour and $4 for each subsequent hour. For those waiting to collect arriving passengers, the Cell Phone Waiting Lot remains a free, 24/7 option equipped with complimentary Wi-Fi. Furthermore, the airport stated that key construction activities will be scheduled overnight whenever feasible to minimize disruptions.
The Terminal Development Project at SAT reflects a broader trend among mid-sized U.S. airports racing to modernize aging infrastructure while accommodating surging passenger demand. The ELEVATE/SAT initiative is particularly notable for its emphasis on accessibility,such as the zero-curb transition,which aligns with modern inclusive design standards. By prioritizing barrier-free access and weather-protected canopies, San Antonio is positioning its facilities to compete more effectively for both domestic and international routes, ultimately driving regional economic development. Phase I of the terminal curbside lane closures is scheduled to begin on March 23, 2026, according to the airport’s press release.
Two of the four lanes at the far end of both the upper and lower levels of Terminal B will be closed during the initial phase.
The airport recommends using the Short-Term Parking Garage, which costs $5 for the first hour and $4 for each additional hour, or the free, 24/7 Cell Phone Waiting Lot.
