No, the Artboard in AI has been fixed at 227 inches for some time. Just work in scale.
Thanks Larry for responding, I had a feeling that was going to be the

AI does not allow working in scales. It is not a CAD program. It only allows working in 1:1, so I'm not sure what Larry is talking about. Perhaps there is a plug-in that allows working in scale?
that's like saying paper does not allow working in scales.
CADtools allows you to set up scales.
Larry, I don't think you know what is meant by "working in scales" or otherwise you would not have made such an odd comment. I don't really feel like defining it here, but suffice to say that many things do not scale linearly in a program like AI that is not designed for anything other than 1:1 layout. Many effects don't scale, for example, even if you check the box. Then there is problem of having to remember to do a mathematical action on every line weight, width, height, font size, font leading, font spacing and so on. Fonts do not always scale linearly either; often the text flow changes. You only have a to miss one math step to have a ruined output. The printer has to take the extra step, too, on the production side. With a program that allows working in scale you just draw at full size and all of that is taken care of automatically.
True, there is no “scale” setting in Illustrator. But I think what Larry was referring to is the very common practice of designer’s designing "at scale".
If a designer’s final printed piece were wider than Illustrator’s artboard limit they will (typically) design it at "quarter scale". e.g. A 330 inch wide design would be laid out as 82.5 inches. This scale designation would be included when you delivered the final files to the service bureau, which would then “scale up” when printing.
Again, this is not a setting or something done automatically; the pre-press person must manually scale up the file. All effects most certainly do scale correctly if you deliver as a properly flattened PDF file.
