Tunnel boring machine resumes digging in Seattle

An August 20, 2013 aerial view of the worksite where Bertha, the world's largest tunnel-boring machine is, shows that progress has been slow since it started digging on July 30, 2013. Washington State Department of Transportation said on their website that the machine was slowed by a 15-foot thick wall of concrete, which it broke through last week.

The world’s largest tunnel boring machine has resumed digging its way under downtown Seattle.

Worked resumed at 4:48 a.m. Monday, after being shut down since Aug. 20 by a labor dispute, said Transportation Department spokeswoman KaDeena Yerkan. The Longshore union had put up a picket line in a dispute with another union over four jobs moving excavated dirt.
Yerkan says operators have some options for making up the lost time.

The tunnel project is part of the state’s overall $3.1 billion plan to replace the Alaskan Way Viaduct, the double deck highway along the downtown Seattle waterfront.

The $80 million machine known as Bertha began digging July 30 on a nearly 2-mile tunnel project expected to take 14 months. The 58-foot diameter tunnel is scheduled to open in late 2015.
