Welcome centers, also commonly known as visitors' centers, visitor information centers, or tourist information centers, are buildings located at either entrances to states on major ports of entry, such as interstates or major highways, e.g. U.S. Routes or state highways, or in strategic cities within regions of a state, e.g. Southern California, Southwest Colorado, East Tennessee, or the South County region of Rhode Island. These welcome centers, which first opened on May 4, 1935 next to U.S. Route 12 in New Buffalo, Michigan, are locations that serve as a rest area for motorists, a source of information for tourists or new residents that enter a state or a region of a state, and a showcase for the state.[1][2] These features make welcome centers, visitors centers, and service plazas, which are similar to welcome centers, distinct from rest areas. In Alaska and Hawaii, their unique geographical locations preclude them from having welcome centers as known in the rest of the U.S.
