A retail shopping mall operates in southern Casa Grande. Phase one of The Promenade at Casa Grande opened on November 16, 2007. Built by Westcor and the Pederson Group, it is similar to Desert Ridge Marketplace (an outdoor shopping center in northeast Phoenix). The Promenade at Casa Grande is an outdoor mall, built on a patch of desert, and contains nearly a million square feet. An additional $11 million was spent by the city to fund the reconstruction of the Florence Blvd./I-10 freeway overpass.
