    What stopped Big Bertha?
    It was thought that several cutting blades were damaged by striking a steel pipe that had been used to measure groundwater in 2002 around the Alaskan Way Viaduct. However, subsequent investigation revealed that portions of the main bearing seal system were damaged, causing the bearing to overheat during operation.
