Starting March 23, 2026, travelers passing through San Antonio International Airport will notice something different — and if you’re not expecting it, it could add real time to your trip. Two of the four curbside lanes at Terminal B are closing, and this is just the beginning of what airport officials are calling a transformative era for one of Texas’s busiest air hubs.
The lane closures mark the official launch of Phase I of the SAT Terminal Development Project, a large-scale construction initiative tied to the broader ELEVATE/SAT program. The goal is to reshape San Antonio International Airport into a more modern, efficient, and accessible facility — one built to handle the passenger volumes the city is already seeing and expects to keep growing.
If you fly in or out of SAT regularly, or if you’re picking someone up at Terminal B in the coming weeks, here’s what you need to know before you go.
What the SAT Terminal Development Project Actually Is
The SAT Terminal Development Project is not a simple renovation. It’s a comprehensive overhaul of the airport’s infrastructure, designed to accommodate record-breaking passenger growth while also improving the day-to-day experience for everyone who walks through those doors.
The centerpiece of the long-term plan is the construction of a brand-new Terminal C. To make that happen, foundational roadway work has to come first — which is exactly what Phase I is designed to accomplish. The curbside lane closures at Terminal B are directly connected to that roadway preparation work.
The project sits under the umbrella of the ELEVATE/SAT initiative, which officials have described as a mission to meet current travel demand while also strengthening San Antonio’s broader economy. Better airport infrastructure means more routes, more airlines, more business travel, and more tourism dollars flowing into the city.
Phase I Details: What’s Closing and When
The changes beginning March 23, 2026 are specific and worth understanding before you head to the airport. This isn’t a full closure — but it is a meaningful reduction in available curbside capacity at one of the airport’s main terminals.
| Location | Current Lanes | Lanes Closing | Lanes Remaining | Start Date |
|---|---|---|---|---|
| Terminal B — Upper Level | 4 | 2 (far end) | 2 | March 23, 2026 |
| Terminal B — Lower Level | 4 | 2 (far end) | 2 | March 23, 2026 |
The closures affect both the upper and lower levels of Terminal B, with the two lanes at the far end of each level being taken offline. The remaining two lanes on each level will stay open to keep traffic moving, but congestion is a real possibility — especially during peak departure and arrival windows.
- The closed lanes are at the far end of both the upper and lower levels of Terminal B
- Roadway work in those areas will support the future Terminal C construction
- The project includes new roadways and improved accessibility features
- The work is part of the larger ELEVATE/SAT initiative tied to passenger growth goals
Why This Matters More Than a Typical Construction Notice
Airport construction notices tend to get ignored — and then people get caught off guard. This one is worth paying attention to because Terminal B curbside access is a high-traffic zone, and cutting available lanes in half during an active construction phase can create bottlenecks that ripple outward into the main airport roadway loop.
The reason the project is happening at all says something important about where San Antonio stands as a travel market. Officials have cited record-breaking passenger growth as a driving force behind ELEVATE/SAT. The airport’s existing infrastructure was not built for the volume it’s currently handling, and without investment now, that gap only widens.
The development plan addresses three core areas: a new terminal building, improved roadways, and enhanced accessibility features. Each of those elements is designed to make the airport work better not just for the average traveler, but for passengers who rely on accessible infrastructure to move through the airport safely and independently.
Who Feels This First — and How to Plan Around It
The passengers most immediately affected are anyone dropping off or picking up at Terminal B starting the week of March 23. With half the curbside lanes closed, the practical advice is straightforward: give yourself more time than usual, and consider whether cell phone lot waiting or remote drop-off points might help you avoid the crunch.
Rideshare drivers and taxis working the Terminal B zone will also feel the pressure. Fewer lanes mean less room to queue, and during busy morning or evening travel periods, that can translate into longer wait times for passengers standing at the curb.
Travelers with mobility needs should pay particular attention. While the project’s long-term goals include improved accessibility features, the construction phase itself may require navigating around active work zones — something worth factoring into your plans if you or someone you’re traveling with needs extra time or assistance.
What Comes Next for San Antonio International Airport
Phase I is explicitly framed as the beginning of a larger transformation. The roadway work now underway is laying the groundwork for Terminal C, which represents the most significant expansion in the airport’s development plan. The full scope of the ELEVATE/SAT initiative is designed to carry SAT forward as passenger demand continues to climb.
Officials have positioned this project as critical not just for the airport itself, but for San Antonio’s economic competitiveness. A modern, high-capacity airport with improved road access and better terminal facilities makes the city more attractive to airlines considering new routes and to businesses evaluating where to locate operations.
The timeline for subsequent phases and the full Terminal C opening has not been confirmed in available reporting at this stage. What is confirmed is that the construction process is now active, and travelers should expect the airport environment at Terminal B to evolve significantly over the coming months and years.
