Fourth Avenue Merchants Association

The Historic Fourth Avenue Business District is directly northeast of and adjacent to downtown, Tucson, Arizona and part of our thriving City Center.

Fourth Avenue became a commercial district after the construction of the Fourth Avenue Underpass in 1916. In 2016, the Avenue’s 100th anniversary, the North Fourth Avenue Merchants Association requested Poster Frost Mirto (Corky Poster, Charles Pifer, and Jennifer Levstik) in cooperation with the City of Tucson (Jonathan Mabry), to nominate Fourth Avenue Commercial Historic District to the National Register of Historic Places.
