Workers in Osaka, Japan, are nearly finished making a giant tunnel drill for Seattle’s new waterfront state Route 99 tunnel.
The Seattle Times said the world-record 57.5-foot-diameter drill is scheduled to dig below Seattle next year.
The giant cutter head will be attached to a machine that is longer than a football field.
The team at Hitachi-Zosen will test the machine before the state Department of Transportation formally accepts it at a ceremony in December.
Then the drill will be dismantled into 41 sections and shipped to Seattle in March. Drilling of the two-mile tunnel is scheduled to start in June.The Associated Press
