Bertha, the world’s largest tunnel-boring machine went down from overheating in late January, one-tenth of the way through digging the 1.7-mile State Route 99 tunnel which will carry a double-deck highway and replace the SR 99 Alaskan Way Viaduct. Water and sand clogged the machine’s cutterhead openings and penetrated seven rubber seals meant to protect the main bearing. In repairing the machine, crews will install 216 steel ribs and plates that will add 86 tons of reinforcement to the 7,000-ton machine’s drive block and cutter drive.Elsewhere in Seattle, one man has figured out how to dig tunnels without giant machines, but the same idiot fagass "government" is trying to stop him from digging because he hasn't acquired the necessary endangered-species permissions:
But to make those repairs, workers are in the process of digging a pit 120 feet deep to access the machine before pulling its 630-ton cutterhead, drive axle and bearing to the surface in order to replace the bearing and add the steel reinforcements. The pit was initially expected to be completed by the end of this month, but construction is now expected to last into August.
Neighbors who live near Cheasty Boulevard South say they've complained about a man who has dug up extensive ditches in the environmentally protected Cheasty Greenspace.
