Having a look at Google Maps, I noticed that B110 and C110 are in completely different spots, with one being in northern Tasmania and the other in the Central Highlands. Is there any history affiliated with this, or is it just one of Tassie's stupid mistakes. I know tassie also has an A10 and a B10, but unlike this they're parallel, like M23/A23 or the UK. And if the reason is, it was out of zone
it makes sense, but all the C11x are in the north, and them running out of B routes isn't really a good reason, since there's a bunch of spare numbers after 68.
