One option is for Seattle to just leave Bertha there, entombed and mothballed.* That way a future feudal society will discover it, reactivate its systems** and use it in wars against neighbouring city-states. Having first dealt with the descendents of the original crew who were trapped within the machine when it was sealed off. Why is there yet no dystopian SF novel with this plot?
Fortunately the future Seattle will have the Oregon Realm of Wicca to its south as a buffer zone shielding it from Emperor Norton VII's attempts to annex it into the San Franciscan Empire. IN ACCORDANCE WITH
However, I am skeptical about the entire story, if only because Bertha is depicted as resembling the circular scraping mouth of a lamprey fitted onto a giant fleshlight. This MAKES NO SENSE. Any fule kno that the canonical design for a tunnelling machine employs a helicoidal cone.
More likely the official story is a cover-up. History proves again and again that Bertha has probably run into a long-buried alien spaceship -- a relic of the Martian campaign to pass on their traits to our hominid ancestors -- and the authorities are stalling, worried that one wrong move will activate the ship's long-dormant psionic energies, with the resultant mass hysteria and genocidal rioting and cities on flame. This ALWAYS HAPPENS. It must be a tradition, or an old charter or something.

* The mothballs are necessary to avoid moth problems.** I assume that Bertha is nuclear powered. If not, WHY NOT.
