Sam White Bridge

So last year, as a part of the massive I-15 Core project which is building/re-building 63 bridges, the largest bridge move in the western hemisphere took place when the Sam White Bridge was moved into its final location. Now I am trying to remember, but I'm pretty sure as my dad and I were adding things all together we estimated the bridge weighed 3 million pounds. It started  at around 11pm and we had to leave at 3am but they finished about an hour or so later. But here are some pictures I took while we walked around.

On this shot you can almost see how long this beast is, it is massive.

Here is a shot at the SPMT (self propelled modular transports), you can see the huge beams necessary to hold it all together, at one point those beams started shaking up and down...they stopped for a while before moving again haha, guess they had to tweak some things.
