SR520 Eastern Highrise

This is the easternmost part of the floating section of the SR520 bridge. Airtight concrete pontoons support the mass of the bridge, though they are reaching the end of their design life and the bridge is quite vulnerable to sinking in a winter storm.

The span under which most marine traffic passes is to the left. It has an impressive set of expansion joints to allow the bridge deck to move with respect to its anchor on Evergreen Point.

That's an odd design. I would have expected a floating bridge to use more balloons. In particular, I would have expected to be constructed mainly from the long balloons that clowns contort into shapes at children's parties... perhaps some duckies or puppy dogs?
