Texas Triangle
The Texas Triangle is one of eleven Megaregions in the United
States. The term comes from the fact that the three main cities in the Texas Triangle are connected by a highway system Interstate 45, Interstate 10, and Interstate 35 that forms a triangle when connected.
The Texas Triangle contains 5 of the 20 biggest cities in the US, and is home to more than 70% of all Texans (pop 13.8 million).
The Triangle is anchored by the metropolitan areas of Houston, San Antonio, Dallas-Fort Worth, and Austin. Source:
