I’ve written a time or two before about the extremely aging elevated highway in Seattle that was severely damaged 18 years ago in a severe earthquake. For the next several years after the quake, state and local governments fought over how to replace the cracked and sinking structure. A deal was reached, laws passed, and the then governor signed it. At the signing ceremony, she said that at the advice of the engineers, no matter how long the replacement tunnel took to build, the highway was definitely coming down no later than 2012…
…and here we are, seven years later, and three weeks ago said highway was finally closed. This week, the tunnel finally opened for traffic. Coincidentally on the first day of real winter weather we got this year. And then the process of taking down the unsafe structure—packing most of the rubble into a much older tunnel that, it turns out, is just as rickety as the old elevated highway and needs to just be filled and sealed—has finally begun.
I have found myself not just biting my tongue a lot reading commentary by some acquaintances about why, oh why, the ugly structure that hasn’t adequately served the region’s transportation needs for the last, oh, 50 years of its existence isn’t being replaced by something even bigger and uglier.
Fortunately, a friend has posted a much more reasoned and comprehensive explanation (and linked to an impressive number of pictures she took at the day this weekend the public was allowed to walk on the old elevated structure and through the new tunnel). So go read Dara’s take on this, including a really nice explanation of the why the highway became obsolete only a few years after being built: So long to the viaduct!
