Bertha Free, Ready for Repair

Machine digging the Alaskan Way Viaduct is ready to be dismantled and removed for repair

Mar 5, 2015

Bertha, the machine that was supposed to dig the Alaskan Way Viaduct replacement tunnel, has traveled 57 feet since February 17 and has finally made it to a tunnel access pit. Bertha, which was damaged in 2013 while digging the tunnel, will be taken apart, removed from the pit and then repaired. The process could take several weeks.

This wide shot shows the giant 'super crane' used to first pull the 4-million-pound cutter head out of the ground and now to lower it back in.
