This is an amazingly crisp and clear photo of the welcome arch by Union Station in Denver. This photo looks out towards 17th Street. Denver’s famous Welcome or Mizpah Arch was built in front of Union Station on 17th Street just west of Wynkoop Street; the arch was formally dedicated on July 4, 1906. The Welcome or Mizpah Arch was dismantled on December 7, 1931, after being deemed a traffic hazard. Built by a consortium of local business interests for $22,500, the arch used 70 tons of steel and cladding and 2,194 light bulbs.
