The three cities that make up a megalopolis along the Pacific coast are Los Angeles, San Francisco, and Seattle. This region is known as the West Coast megalopolis due to the urban sprawl and interconnectedness of these major cities along the coast.

A megalopolis is a basically a very large city, that connects with other large cities. Houston, San Antonio, and Austin is considered a megalopolis, but the state of Texas itself is not, because it is a state and not all of its cities are connected in such a way. For example, El Paso is on the far west side of Texas, is considered a major city, but is not connected to any other major cities in Texas.
