One day soon there will be a giant tunnel under Seattle and that tunnel will bored by Bertha, who has finally arrived from Japan after a month-long journey.

Even though the arrival is over, the show isn't. WSDOT has a handy guide to the best places to see Bertha as they get her situated and put together. By the end of April, Bertha's 41 pieces will be five stories long, 57.5 feet in diameter, and weigh around 6,700 tons.
