A $156 Million Road Project Near the Airport Is Coming. Here's What San Antonio Homeowners Need to Know.

If you live near San Antonio International Airport, own a home in the Sunset Hills, Oak Park, or Northwood areas, or are eyeing a property anywhere along the Loop 410 and US 281 corridor, a major construction project is about to become part of your daily reality. TxDOT has confirmed a $156 million overhaul of this stretch that will run from fall 2026 all the way through 2029. That is not a pothole repair. That is a full-scale rebuild of one of the busiest intersections in the city.

The project covers 4.3 miles of Loop 410 from West Avenue to Broadway and 2.7 miles of US 281 from Loop 410 north to East Nakoma Drive. The work includes rebuilding ramps, adding auxiliary lanes, and constructing a southbound collector-distributor road on US 281. The goal is to untangle one of the most congested interchanges in Bexar County, a spot that has frustrated commuters, delivery drivers, and airport travelers for years.

So what does this mean if you own a home in the ZIP codes and neighborhoods closest to the work zone? In the short term, expect disruption. Traffic on Loop 410 and 281 during construction will be rerouted, slowed, and complicated in ways that change commute times and cut-through patterns. Neighborhoods like Windcrest, Alamo Heights, and the communities just north of the interchange along US 281 near East Nakoma Drive will likely see more local traffic as drivers look for alternatives. If you live in those areas, now is a good time to identify your backup routes and plan ahead before the heavier construction phases begin.

For homeowners specifically, there is a real upside on the other side of this project. Infrastructure improvements of this scale typically increase the long-term appeal and accessibility of nearby neighborhoods. When a major interchange is rebuilt and modernized, properties that sit close to it often see improved connectivity without the same level of congestion that drove buyers away before. Areas along US 281 north of Loop 410, including communities in the 78216 and 78209 ZIP codes, stand to benefit from a smoother, more functional corridor once the work is complete.

If you are thinking about selling between now and 2029, be honest with buyers about where the construction is and how it may affect access to your property. Buyers do their homework, and a seller who addresses it directly builds more trust than one who avoids the topic. That said, a patient buyer who understands the long-term value of the corridor improvements may actually see your home as a smart buy right now, before the area fully reflects the investment being made around it.

Buyers considering homes near the airport, along Nacogdoches Road, Harry Wurzbach, or the Broadway corridor should factor construction timelines into their decision-making. If walkability and low-traffic streets matter to you, a home directly adjacent to the construction zone may feel less appealing through 2029. But if you are a longer-term buyer who can tolerate a few years of inconvenience for the payoff of an upgraded corridor, this window could be a reasonable time to get into a neighborhood before values reflect the finished project.

For renters and landlords in the area, this is worth watching closely. Rental demand near the airport and the medical and business corridors along 281 tends to stay relatively stable regardless of construction. However, landlords may find that properties directly impacted by noise or access issues need to be priced and marketed accordingly during the construction years. Transparency about what is happening nearby will serve landlords better than hoping tenants do not notice the orange barrels outside.

Families with children in North East Independent School District or Alamo Heights ISD should also think through school drop-off and pickup logistics, since construction-related traffic changes can affect morning and afternoon routines around the interchange.

The bottom line is that this project is a genuine investment in San Antonio's infrastructure, and the communities near Loop 410 and US 281 will be better for it when it is finished. Getting there will take patience, flexibility, and good planning. If you own property in this part of the city, now is the time to start thinking about how the next three years of construction will shape your living situation, your commute, and ultimately the long-term value of your home.
