Due to the efforts of numerous local historic preservationists, Tucson's unique North Fourth Avenue is now recognized nationally for its history and architecture. The new National Register Historic District includes 50 contributing properties that date between 1903 and 1967.
Fourth Avenue represents one of the first continuously viable commercial areas outside of Downtown Tucson. Notable architecture includes a variety of early 20th century urban forms.
