Bertha (tunnel boring machine)
Bertha is a 57-foot-diameter (17.4 m) tunnel boring machine built specifically for the Washington State Department of Transportation's (WSDOT) Alaskan Way Viaduct replacement tunnel project in Seattle. It was made by Hitachi Zosen Sakai Works in Osaka, Japan, and the machine's assembly was completed in Seattle in June 2013. Tunnel boring began on July 30, 2013, with the machine originally scheduled to complete the tunnel in December 2015.
On December 6, 2013, work was halted approximately 1,083 feet (330 m) into the planned 9,270-foot-long (2,830 m) route because of an unexpected impediment. Initially, it was thought that the machine had damaged several of its cutting blades after encountering a steel pipe that was used to measure groundwater in 2002 around the Alaskan Way Viaduct. However, subsequent investigations revealed that portions of the main bearing seal system were damaged, which caused the bearing to overheat during operation. Over the next two years, a recovery pit was dug from the surface in order to access and lift the machine's cutterhead for repair and partial replacement in 2015.
Bertha resumed tunnel boring on December 22, 2015, but was stopped in early January 2016 after a tethered barge in Elliott Bay damaged nearby piers and a sinkhole opened near the project site. Governor Jay Inslee halted all work on the tunnel on January 14, 2016, citing concern over public safety after the sinkhole incident. Digging resumed on February 23, but was halted again for maintenance and inspections late in March. Bertha resumed tunneling on Friday, April 29, 2016, digging under the Alaskan Way Viaduct. Tunnel boring was completed on April 4, 2017, with Bertha's cutterhead breaking into a disassembly vault at the tunnel's north portal in South Lake Union.
In December 2015, WSDOT estimated that the tunnel would be completed and open to traffic in early 2018. The estimate was revised in July 2016 to open in early 2019; an estimated $223 million in cost overruns stem from the two-year delay of the machine.
The name Bertha, after Seattle's first female mayor, Bertha Knight Landes, was chosen by a panel (that included the Governor and Transportation Secretary) from 150 submissions from kindergarten through 12th graders, who were asked to submit female names with Washington state heritage. The winning entry, which was submitted by two elementary schools in Poulsbo and Hoquiam, was selected in December 2012.
In March 2016, regional transit agency Sound Transit decided to drop names for its own tunnel boring machines, used for smaller light rail tunnels, citing unwanted association and confusion with Bertha, especially the machine "Brenda" used on the Northgate Link Extension and University Link Tunnel.
Bertha was designed and manufactured by Hitachi Zosen Sakai Works of Osaka, Japan, and is the world's largest earth pressure balance tunnel boring machine, at a cutterhead diameter of 57.5 feet (17.5 m) across. The machine is 326 feet (99 m) long and weighs 6,700 short tons (6,100 t). The machine itself cost $80 million and is owned by Seattle Tunnel Partners, the project contractors. Seattle Tunnel Partners is a joint venture of New York-based Dragados USA, a wholly owned subsidiary of Dragados, S.A., the construction division of ACS Group of Spain; and Tutor Perini Corporation, based in Sylmar, California. 
Hitachi Zosen held a completion ceremony for the machine, performed at the same time as the naming ceremony, in Osaka, Japan, on December 20, 2012. It was shipped three months later to the Port of Seattle in 41 sections, arriving on April 2, 2013.
