Mullan Road

Many are familiar with the Mullan Road; the road that traverses the expanse from Walla Walla, Washington to Fort Benton, Montana.  
      Missoulians, for instance, routinely use Mullan to access their homes, or shopping or dining on Reserve Street. The Missoula County Detention Center's located there, as well.
       But perhaps you've never given a second thought to the road's namesake, its origin, or the impacts it's had on the region.
