The January issue of Houston Business proposed that the Texas Triangle metro areas of Austin, Dallas/Fort Worth, Houston and San Antonio exist as distinct cities largely because of Texas geography. With a long, navigable river reaching the heart of the state or a deep saltwater bay or other inlet making Waco or Temple a seaport, many of the roles played by the Triangle cities could have been combined at a single location. Combining Houston’s port, Dallas’ inland distribution function, San Antonio’s reach into deep South Texas and northern Mexico, and even the state’s political capital into one place could have produced a Third Coast megalopolis to rival New York, Los Angeles and Chicago.
