Sellwood Bridge Move

On January 19, the 87 year old Sellwood Bridge began a 12 hour move to its temporary new home, a few yards downstream from its original location.  The 3,400 ton structure was slowly pushed north by a network of 50 hydraulic jacks onto five temporary support piers.  Making the whole operation even more complex is the fact that the bridge had to be moved at a skewed angle, with the east end moving 33 feet northward and the west end moving 66 feet.  With the bridge diverting the traffic, work can now begin on its replacement.

Here are my photos and sketches:
