The Downtown Underground is a subterranean complex serving storage, warehouse/distribution, light manufacturing as well as office applications. Underground space is economical--great for start-up companies or businesses desiring a modest overhead. No gas utilities and year-round dry loading conditions make underground space unique and affordable. The Downtown Underground entrance is located on 31st Street between SW Boulevard & SW Trafficway. Minutes from I-35, the underground offers a great center-city location at the hub of the city's major arteries.
