Another Reason to Stop, Bertha has Sinkhole for a Neighbor

While Bertha waits for fixes to the barges that carry away the dirt, another anomaly arrived. A 250 cubic yard sinkhole appeared just west of the site. WSDOT filled it with concrete. The ground seems stable. Everything should work out fine. The tunnel and Bertha are fine. The Viaduct is fine. The hole was the sort of thing that was anticipated, but is unfortunate at best. Maybe the soil was too fine? In the meantime, Bertha continues to idle, as does the progress.
