Sinkhole in Downtown Seattle After BERTHA Begins to Move Again

This project has been a disaster since the beginning. I am so thankful I don't have to travel on the viaduct every day anymore.

'Approximately two hours [after Bertha started drilling again], a sinkhole developed within STP’s work zone near South Main Street, about 35 feet north of the access pit. It is located more than 100 feet south of the cutterhead's current location, in ground that crews mined through last week. STP filled the sinkhole overnight with 250 cubic yards of concrete.'
