I don't design bridges, but this seems a bit extreme

560k on a Bridge

This does not surprise me. I routinely get called out to inspect bridges that were hit by an overheight truck and it's almost always on a Friday. These companies have no regard for anyone else except their bottom dollar.
I've had the same thing with over weight vehicles. Thankfully some people were alerted and got some super loads off the road until we could do the load ratings and get them approved.
I've dealt with some large loads in the 350k range but not one of that size. Something that size and not spread out would have caused problems. Probably is even damaging the pavement just sitting there.....

Structural
This incident will "blow over" soon. The Rhode Island DOT is having a justified "fit" since Bay Crane did not obtain a permit. Trailers of the type used (16 axle, probably 8 tires per axle) are designed to limit axle loading to legal limits. There "may" be a "problem" only if a structurally deficient bridge had a very long span. Photos of the trailer show:
8 axles ahead of the load
No axles under the load
8 axles behind the load
On bridges with short spans no more than 8 axles will be on a span at one time.
There is news "talk" about disassembling the generator to move it in lighter pieces... that is not going to happen. What is on that trailer in a generator "stator" (not a complete generator) for a multi-hundred megawatt electric generating station. It is basically an iron core with heavy copper windings. The (ligher) rotor is shipped separately. There is nothing about a stator to disassemble short of destroying it's usefulness. If there was, the stator would be shipped as component parts to be assembled on-site.
We had to move a 400 kip stator as short distance on a 12-axle trailer (by a specialty Contractor). Here is a photo of the stator being transferred from a dedicated transport railcar to trailer. I performed planning, contract prep/bid/award, and field construction management for this project.
