So you can see behind me the Amos-Rate bridge is jacked up on 1255 ton hydraulic jacks and they lifted the tracks with the bridge on both sides and they're going to re-grade those tracks level with the bridge and the crossing over a duke street which is actually C-file here. I'll 8 inches higher so that it is in the end it's level with that crossing. But right now the bridge is suspended 10 inches in the air while on these jacks of course with the tracks kind of pulled out of the gravel on both sides they're working carefully but also quickly to secure it clean up under the foundation and then put it back down to inches on top of the new foundation. Well basically just shims on top of the old foundation to cure it in place re-grade the tracks and that should do it. Pretty amazing. You can see enormous 55 ton jacks that they're using to raise the stretch. They're using swell buffies. Not sure what the weight of the bridge is but it's got to be 20 as easy. So it's almost noon on Tuesday, over 29 and they pretty much finished of the raising procedure at the 11 foot 8 bridge. They're thinking the process now securing a bridge on its new foundation and show you the shims that they put in under the structure to raise it 8 inches. There you can see the shims that they put in to raise the structure. They're measuring the grade of the tracks now to see what they have to do to adjust the tracks to the new level of the track.
