Seattle

Mid pic: Tacoma bridge fee booth traffic. Not really a Seattle pic, but clooooose.

Top pic: The curved portion of the Seattle viaduct with its patchwork of metal plates holding it together. This is the weak link in the whole thing. Nothing really underneath this supporting, since the waterfront was filled a kajillion years ago (okay, about 100) and the worms have eaten through the wood. This bridge is not made of wood,obviously, the stuff under-under the pavement is.

Bottom: Back to SoDo. When I was a youngster, Seattle's Interstate 5 freeway had oodles of bridges that went to nowhere. They just ended in mid-air....(they were blocked off... so no risk of taking an airborne ride.) Great planning on someones part, since the infrastructure was created before the cars came. Interesting, since that is not usually what happens in our wishy-washy can't make a decision without three years worth of public meetings where the dog chases its tail over and over and over. This is one of the former overpasses that 'went to nowhere' now going somewhere. And you can drive on it. Risk free.
