SPRING 2015

Light penetrating sidewalk at the Seattle seawall

New sidewalk surface near Pier 50

The “capper” on the superstructure of the rebuilt Elliott Bay Seawall is the new sidewalk comprised of light penetrating surface panels, a key element in the design of the improved habitat zone. Waterfront Seattle’s March 12th weekly progress update highlights this feature, with some video showing the installation south of Colman Dock.

Above is our prior post on the habitat zone construction sequence. And here’s another link to the very informative February 24th Seattle Times article about the purpose and approach on the environmental aspects.

More information and images are available at Seattle DOT’s blogpage. Stay tuned for a feature to be published there about the complex utility scenario – here are some thoughts by Scott about that topic back when the seawall design was completed in late 2013.

Here are some additional photos showing various aspects of the LPS sidewalk – a unique structural element, to be sure.
