One of the major elements of the the Alaskan Way Viaduct Replacement Program will be the gigantic SR 99 tunnel which will host a double-deck roadway under downtown Seattle. In this stunning new photo, you are looking south inside the tunnel dug by Bertha, the SR 99 tunneling machine. It is hard to say less than this tunnel is really enormous.
Just to make sure you won’t miss the little guy in the photo, here is a cropped and zoomed in section of the image above:

As a philly resident, I had really hoped this project would’ve gone more smoothly than it has. It would be amazing if we could replace the current set up of 95 (a massive gulph between Old City and the Delware) with a tunnel.
