The SR 99 tunnel project has been chugging right along since my last post about it in April.
Earlier this month, the 6,700 ton, $80 million tunneling machine was christened Bertha. She was built in Osaka and will soon be shipped to Seattle in 41 pieces. Oh and you can follow her on twitter at BerthaDigsSR99.
My pictures are taken at the south end of the site, which is where Bertha will start digging. Here’s my first picture of the site, from April 2012 followed by pictures from July, September and November.
I don’t have right vocabulary for this, but basically they bored lots of deep holes and put pillars in them and then built the ladder shaped trusses. Then they dug a long pit beneath the trusses and lined the walls of the pit.
This one’s from September.
Here’s an nearly aerial picture taken from the Columbia tower in November. It is one big puddle. In January I’ll try to get a shot of the workers sloshing around in shin-deep mud.
This machinery picture is for you, Dad.
If you’re interested in the project, check out the free exhibit at Milepost31 in Pioneer Square.
