Ca scales?

Not really ran into this problem before, so here goes...
Loading at Roseburg,Or (Exit 123 on I5) heading to Laredo, Tx. Legal load, hopefully legal weight etc.
Here is the "issue"....Easiest/shortest way takes me into Ca on 5, then I was planning on cutting over into Nv. Problem is, I have a 53', fixed 3 axle stretch RGN, with the rear axle at the back of the trailer! I know the rear axle needs to be a maximum of 40' from the kingpin, which is obviously not going to happen on this trailer.
Any scales there for sure? I am showing one @ Mt Shasta on 5, which is before my cutoff.
If it turns out to be overweight, I think I can get permits for the trailer, but legal weight I can't.
I know I can add a load of miles, and run through Or into the back of Ca, but those roads dont look too friendly on the map!

Thoughts/solutions?
Cheers

Thanks!
Yeah, 29' in the well, and neck is flipped up already. Kingpin to center of rear axle, closed and neck up, is 49'6", so screwed either way. 4'6" center to center on the trailer axles, so will still be 45' if I screw with it. Cant remember which axle has the levelling valve on it neither, thinking front, but not for sure.
Not sure if our (lazy) permit gal will be interested in doing that. They dont pay for fuel, so not their problem in their miniscule minds.

"Other place" as in ATS?
If so they wont even talk to us poor old MW drivers....
Looking at the Or maps, looks like I am screwed for running 140 too....love it.

Edit: Any way around the scale on I5, so I can get over to 89 and 44, then onto 395 into Reno?

 

Not really a block per say, but they would just send me to our permit dept. Had a few "route issues" with the blade runs, and got told to address it with our own permit dept. Totally sad when those loads are FOR ATS!
Oh well......Better than having the electronic logs and so on I guess.
