Monday night, April15th, Jumbo's
Fairpartner completed delivery of the SR99 Tunnel Boring Machine (TBM) at Pier 46 in Seattle, Washington.
And by late last Tuesday afternoon, she cleared the Strait of Juan de Fuca, making for Dalian, China.
Resembling the parts of a giant child's toy-set, the next step is to re-assemble the 111,940 m (367 ft) long TBM in the Launch Pit. This is expected to take a few months to complete.
The boring machine is re-assembled from rear to front. Late this afternoon the 3rd car was maneuvered into place riding on two
Goldhofer self-propelled mega axle/mega tired transporters. In a few days, the red track mounted gantry crane will lower the car into the pit.
The support cars following the boring shield, carry a galley, machine shop, and construct the tunnel liner. Once again, the Washington State Department of Transportation has made this multimillion-dollar project accessible to all "sidewalk superintendents" by installing a handful of construction web cameras.
I've installed a button in the right margin, providing a link to WSDOT Construction Cams.
