(Video clip updated late Monday by WSDOT, so we’ve substituted the new “extended” one)
According to an update this morning from WSDOT, the newest schedule from its contractor Seattle Tunnel Partners still says the tunneling machine is expected to start up again next week, two days before Christmas. (WSDOT, meantime, reiterates that it “cannot verify” the schedule.) Meantime, it’s also published the video clip you see above, showing one of the final steps in access-pit preparation before the machine can get going again – backfilling with sand, which started yesterday and is expected to continue all week. This and other prep steps are all detailed, with graphics, on WSDOT’s project website. It’s now been more than two years before the machine overheated and stopped tunneling.
