In this photo made with a fish-eye wide-angle lens, &quot;Bertha,&quot; the massive tunnel-boring machine that is expected to spend the next 14 months drilling a two-mile tunnel to replace the 60-year-old Alaskan Way Viaduct, is shown ready to begin drilling later this month, Saturday, July 20, 2013 in Seattle. The tunnel will replace the viaduct, a double deck highway along the downtown Seattle waterfront. Photo: Ted S. Warren, AP / AP
