This Tuesday, Aug. 2, 2016, handout photo provided by the National Museum of Industrial History shows visitors browsing exhibits on the opening day of the museum, housed in a century-old building at the former Bethlehem Steel plant in Bethlehem, Pa. The National Museum of Industrial History opened Tuesday, Aug. 2, 2016, after nearly 20 years of planning, and the Smithsonian Institution-affiliated museum is located on what was once one of America's largest abandoned industrial sites where it joins the nearby Sands Casino Resort Bethlehem and a thriving arts complex called SteelStacks.
