I hear you Nathan... If one historic bridge can be saved, so can others. Missouri and Pensylvania are wrecking historic bridges, Alaska shouldn't follow their trend. It is always apalling to see UCEB's being put up beside a beautiful and savable truss. The "kaboom" will surely sting, and out of the dust remains the concrete "thing"...
Absolutely pathetic. Nobody can try to tell me this historic bridge is in the way of anything. Don't demolish it... leave it standing next to its replacement as an abandoned historic landmark! It is so simple.
The largest and least populated state in the United States of America, and even here we can't leave the historic bridge standing next to its replacement?! What harm could it possible cause to leave it? Worst thing that could happen is an earthquake splits it in half, and that didn't stop the Million Dollar Bridge.

In going through the doomed bridges listed I came across an article about the loss of this bridge last year. Alaska DOT threw a party topped off by blowing up this bridge to smithereens.
