Now take a video tour of what's really been happening underground with Bertha, the Alaskan Way Viaduct boring machine. Learn the whole Bertha truth as she helps build the underground double deck highway tunnel.
The slow grind stated last Friday, April 29, when Bertha left her maintenance block. As is tradition, Monday morning a hydraulic part malfunctioned and forced crews to stop while Bertha was repaired. After a short rest, Bertha kicked herself into gear and continued to give it her all. What a gal!
Watch as the WSDOT drone maneuvers through the SR99 underground construction zone that looks, dare I say it, like the Death Star.
