Now we’re getting somewhere – The SR 99 tunnel boring machine stands tall

    Prev Next

    Crews in Japan stand in the shadow of what will become the world’s largest-diameter tunnel boring machine. Currently being assembled in Japan, the machine will dig the SR 99 tunnel beneath downtown Seattle starting in summer 2013. Scheduled to open to traffic in late 2015, the tunnel will replace the central waterfront section of the Alaskan Way Viaduct. Learn more about Bertha, the SR 99 tunneling machine, at her webpage or follow her on Twitter @BerthaDigsSR99.

      I think this would be a really cool shot with a tilt shift lens!
