#BerthaBreakthrough is underway

Posted on Apr 4 2017 10:09 AM

Bertha started mining this morning arouind 8 a.m. As of 10 a.m., water and soil conditioners had begun entering the bottom of the pit as the cutterhead began to break through.

Due to heavy traffic, our website has been down intermitently. A livestream of the breakthrough is being carried by most Seattle-area media sites. We'll continue to provide updates here, and on Facebook and Twitter, as the day progresses.
