North America’s Tallest MSE Retaining Wall

[Update Jan 28, 2008] It appears as if the Port of Seattle is in some hot water for some alleged shady dealings with one of the contractors on the project.  More at Seattle Times. [/Update]

Erosion Control magazine has an interesting article on MSE Walls. I think the tie-in of MSE Walls with erosion control is a little questionable (they did mention wall drainage a few times), but the article highlights several interesting projects, particularly the Seattle-Tacoma Airport or Sea-Tac Third Runway Project retaining walls. The West wall for that project is the tallest MSE Wall in North America, 130-ft at its highest point. More after the break. (Photo by Sea-Tac Airport)
