Greyhound is a national bus operator with service throughout the lower 48-states. In some regions, transit agencies are not interconnected and Greyhound (and Amtrak to some extent) is the only mode connecting these cities. In rural areas, some transit agencies provide connecting bus service from various communities to Greyhound bus stops located in larger cities.
Some of the Greyhound terminals are located at or adjacent to major transit centers. Others are located a few blocks away.
