Objects encountered by the SR 99 tunneling machine

That’s one of three photos WSDOT shared late today along with an update on what’s being done to figure out how to get “Bertha,” the Highway 99 tunnel machine, going again, one month after it got stuck. The update says the steel and boulder are some of the items that passed through Bertha and onto its conveyor belt before it stopped moving forward in early December; this section of pipe was removed, too. They still aren’t sure the widely reported pipe is the whole problem. So they’re drilling to continue investigating, as you might have noticed to the west what’s left of the Alaskan Way Viaduct:

Read the entire update here. What this will cost in terms of time and money has not yet been determined, since they say they don’t know yet what it’ll take to get tunneling back on track, but KIRO TV quotes the state Transportation Director as suggesting the tunnel contractor could be held responsible for not clearing the way first.
