People have a lot of questions about Bertha, the massive machine digging the SR 99 tunnel beneath downtown Seattle. What will happen if she hits a 10-foot boulder? When will the roadway inside the tunnel be built? How does Bertha’s conveyor system work? Join us for this month’s speaker series to hear tunneling expert Chris Bambridge, Alaskan Way Viaduct Replacement Program Tunnel Design Engineer, answer the most commonly asked questions, and ask one of your own!
Thursday, Nov. 7
6 to 6:30 p.m.
After the talk, be sure to leave enough time to explore the rest of the First Thursday Art Walk in Pioneer Square. Milepost 31 is open Tuesdays through Saturdays from 11 a.m. to 5 p.m., and stays open until 8 p.m. on First Thursdays. Free parking is available for First Thursday art walk patrons in Pioneer Square. Please visit www.FirstThursdaySeattle.com for more information about participating garages.
And don’t forget you can track Bertha’s journey to Seattle on Twitter by following @BerthaDigsSR99.
