The wider Texas Triangle
The big metros anchor the story. Smaller cities, rural communities and trade gateways complete the picture.
Connections between communities
TxDOT’s map reaches beyond the largest metros, identifying places such as Granbury, Sherman, Waco, Killeen and College Station, plus Gulf Coast connections.
Its Texas Triangle Multimodal Strategic Plan examines how people and goods move across the region. It develops strategies—not a ranked list of individual construction projects.

Planning milestones—not promised project-opening dates. Summer 2026 update ↗The region in numbers
More than 21.8 million people across the four major metro areas. Each brings a different economy and a different set of needs.
Dallas–Fort Worth–Arlington MSA
8,477,157 residents
Finance and logistics meet aerospace, manufacturing and a broad business-services economy.
Houston–Pasadena–The Woodlands MSA
7,904,627 residents
Energy remains an important part of a major metropolitan economy and its industrial connections.
San Antonio–New Braunfels MSA
2,813,140 residents
Tourism, military activity, medical research and business services shape its economic mix.
Austin–Round Rock–San Marcos MSA
2,620,945 residents
Technology and professional services figure prominently in the metro’s growth story.
Population: July 1, 2025 estimates, Census Vintage 2025. Four-MSA sum: 21,815,869—not a total for every broader Triangle definition. Data ↗ · Economic context ↗ · How to read these numbers →
How the idea took shape
A 2007 UT study traces earlier use of the phrase to railroad services, citing historical word research.
The research ↗Southwest begins service linking Dallas, Houston and San Antonio. The airline connection is real; the napkin story is legend.
Airline history ↗UT researchers examine economic integration and the case for coordinated transportation planning.
The study ↗Kinder’s articles explore the Triangle’s potential—and the investments needed to sustain it.
Kinder’s perspective ↗The 1936 reference is reported by a later study; this guide does not claim to identify the phrase’s first author.
Beyond the skyline
The region’s future depends on more than its largest cities. The places and systems between them matter, too.
I-35, I-45 and I-10 form the principal interstate connections. Freight, daily mobility and access to jobs make transportation a regional issue.
TxDOT’s corridor overview ↗Kinder’s policy blueprint treats housing, land use and access to opportunity as part of economic development—not an afterthought.
The policy blueprint ↗Heat, storms and water needs cross jurisdictional lines. Kinder argues that resilience and connections to rural Texas belong in the growth conversation.

Dated evidence, clear geography and links to the original reporting.
The Dallas Fed’s September production index rose to 29.5. It is a survey index—not a 29.5% increase in output or a construction forecast.
Texas A&M’s latest outlook anticipates improving supply-demand balance through summer 2027. Availability still needs a market-by-market look.
The Dallas Fed’s updated metro profiles explain why a common regional story can contain very different local economies.
The people who build the region
A shortage of skilled construction workers can affect a contractor’s schedule. The strongest evidence here is a national workforce survey—not a claim that every Triangle market lacks contractors.
For an owner, the practical question is whether the right team and trades are available for the specific project.
What the workforce evidence says →Space for what comes next
A region works through the smaller spaces, suppliers and service businesses around its major employers.
Office, showroom, shop and warehouse functions can share a practical footprint. Texas A&M’s manufacturing study identifies a role for smaller flex buildings.
Start with the process: equipment, power, receiving and how the operation might change. The building should follow the work—not just a square-foot target.
Stored contents, temperature and humidity requirements should guide the plan. This is a distinct building use, not a shortage established by warehouse statistics.
