The normally sedate city of Seattle sounded more like the set of a science fiction epic today as the world’s largest boring machine roared and screeched its way into the open air. The tunnel boring machine, better known as “Bertha” cut through a wall of reinforced in the shadow of the city’s iconic Space Needle at about 11:15 am, completing the last few feet of a tunnel more than 9,720 ft (2,963 m) long as part of project to build a new road link between the southern and northern halves of the city. New Atlas was there to witness it.
