the Portland ESCSO tunnel is ~150' below the streets of Portland on the eastside of the Willamette River and runs from 17th& McLoughlin to Swan Island and is ~22' finished diameter and SIX miles long. This is a collection of photos as it is built.
The slideshow is the easiest way to view the images full size. On the slideshow pages, there are a couple controls like the background color, the timing, and the transition. Play with these controls until you find what you like the best. Close the slideshow window by clicking on the X in the upper right corner. This will take you back to the “gallery view.” Click on “Brews Photos” in the upper left corner to see all the galleries.
