Bertha, the massive tunnel-boring machine, is stuck underneath Seattle and Seattle Tunnel Partners must dig a giant access shaft in front of Bertha to lift her out and fix her. New York Times reporter Kirk Johnson’s story is here and some pictures I shot for the article are below.
Workers wait while a large metal pipe, used for digging, is moved into place at a construction site where a large shaft is being dug to access “Bertha,” the tunnel-boring machine that sits below and needs repairs, in Seattle, Wash. on Friday, July 25, 2014. The new access shaft will be 120 feet deep and 80 feet wide, and is built by creating an outer wall of smaller shafts, each filled with concrete and interlocking. (David Ryder for The New York Times)

I want to tweet about your story and work with your beautiful image of the rebar (second form last), how can I do that and help drive traffic an interest to your site?
Hey, thanks Drew. What do you mean work with the image? Thanks for the comments. Cheers, David
