A third big piece of the Highway 99 tunneling machine was lifted up from the repair-access pit today – and that means just one BIG lift to go, the cutterhead, for which Seattle Tunnel Partners will use that large red assembly you’ve been seeing next to the Viaduct. It’s shown in this next photo shared with WSB by Gatewood photographer/pilot Long Bach Nguyen (taken before today’s lift):
The previous two lifts were on Thursday – with the big half-circle piece you see toward left center of the LBN photo – and on Saturday. No exact date announced yet for the cutterhead to be brought out. STP has said that if repairs go well, it hopes to be tunneling again in August.
