Enormous Tunneling Machine 'Bertha' Blocked By 'The Object'

An anonymous reader sends word that 'Bertha,' the world's largest tunneling machine, which is currently boring a passage beneath Seattle's waterfront, has been forced stop. The 57.5ft diameter machine has encountered an unknown obstruction known as "the object." "The object’s composition and provenance remain unknown almost two weeks after first contact because in a state-of-the-art tunneling machine, as it turns out, you can’t exactly poke your head out the window and look. 'What we’re focusing on now is creating conditions that will allow us to enter the chamber behind the cutter head and see what the situation is,' [said project manager Chris Dixon]. Mr. Dixon said he felt pretty confident that the blockage will turn out to be nothing more or less romantic than a giant boulder, perhaps left over from the Ice Age glaciers that scoured and crushed this corner of the continent 17,000 years ago. But the unknown is a tantalizing subject. Some residents said they believe, or want to believe, that a piece of old Seattle, buried in the pell-mell rush of city-building in the 1800s, when a mucky waterfront wetland was filled in to make room for commerce, could be Bertha’s big trouble. That theory is bolstered by the fact that the blocked tunnel section is also in the shallowest portion of the route, with the top of the machine only around 45 feet below street grade."
