    Program – Alaskan Way Replacement Program

    Presented by WSDOT

    For our first ISA event of the 2015-2016 year we will meet Bertha up close 

    [WSDOT] In summer 2013, Bertha, the world’s largest tunneling machine, began digging the SR 99 tunnel beneath downtown Seattle. In December 2013, Seattle Tunnel Partners, the contracting team hired to design and build the tunnel, stopped excavation approximately 1,000 feet into the dig after measuring increased temperatures in the tunneling machine. While investigating the cause of the high temperatures, STP discovered damage to the machine’s seal system and contamination within the main bearing. STP and manufacturer Hitachi Zosen are currently repairing and enhancing the machine.

    Bertha returning to the access pit

    On Aug. 25, 2015, after repairing and enhancing the machine at the surface, Seattle Tunnel Partners and crane crews from Mammoet successfully lowered the machine's 2,000-ton front end to a platform at the bottom of the access pit. Crews are now connecting the piece to the portion of the machine that remains in the ground. Three additional pieces will be lowered into the 120-foot-deep pit in the coming days.

    PDH (Professional Development Hours): 1

    Tours begin at Milepost 31, 211 First Ave. S. in Pioneer Square in Seattle. Please arrive at least five minutes prior to the scheduled tour time.

    The tours are ½ mile round trip. Visitors must be able walk over uneven ground and climb up and down 50 stairs.

    Tours last one hour.
