Boring Bertha: This photo provided by the Washington state Department of Transportation shows the massive tunnel boring machine called Bertha at the bottom of a rescue pit Wednesday in Seattle. The machine is now in position to be taken apart so it can be repaired. Transportation officials say the broken machine reached a stopping point inside the rescue pit late Tuesday, clearing the way for workers to start the disassembly process. The tunnel is being built to replace the Alaskan Way Viaduct, damaged in a 2001 earthquake. The machine started digging in the summer of 2013, but broke down in December of that year.
