BERTHA BREAKTHROUGH WATCH: Highway 99 tunneling machine on maintenance stop

We’ve been watching the Highway 99 tunneling-machine update page, now that “Bertha” is getting close to breakthrough, and just noticed that today’s update says 219 feet to go – same as yesterday. WSDOT explains via Twitter that “(Seattle Tunnel Partners) is wrapping up routine maintenance and plans to resume mining tomorrow.” So for those who speculated breakthrough might happen this week – highly unlikely.

    If Bertha sees its shadow will it pop back in the hole for another 6 weeks? What’s another few weeks when you are already years behind schedule.

    At least it’s getting done. 

    Would be cool with a walking tour thru it before they build the split deck to see the engineering in person.

    I haven’t seen any “boondoggle!” comments regarding Bertha lately……..

    There are a whole lot more bigger boondoggles to worry about now…

Sorry, comment time is over.
