Many Working Helenans (approx. 18%) work for agencies of the state government. When in Helena, most people visit the local walking mall. It was completed in the early 1980s after Urban Renewal and the Model Cities Program in the early 1970s had removed many historic buildings from the downtown district. During the next decade, a three-block shopping district was renovated that followed the original Last Chance Gulch. A small artificial stream runs along most of the walking mall to represent the underground springs that originally flowed above ground in parts of the Gulch.
