The north end of the bored tunnel

A couple blocks east of the Space Needle crews have completed excavation of the 85 foot-deep pit where Bertha, the SR 99 tunneling machine, will complete her 1.7 mile-long journey under downtown Seattle. Learn more about the Alaskan Way Viaduct Replacement Program at www.alaskanwayviaduct.org or follow Bertha on Twitter @BerthaDigsSR99.
