This has been a long time Seattle project. Replace the freeway that runs over the top of the nice shoreline tourist destination along the waterfront of Seattle. We had to park under the freeway and
walk to the crossing. Noisy and a bit scary. Map above shows the shoreline district and the planned destination of Bertha the tunnel boring machine.
This picture was taken today. Bertha is just on the other side. They've had a tv camera
on it and it is noisy, men yelling and then a gush of water came out the bottom. Then dust everywhere. They had to move news folks back and start spraying all the dust with water.
And Bertha arrived!!!
Now to build a road thru it.
