There's a much more important issue in this case. In most cases, the government does not own the land under the road, but possesses an easement by which the property owner grants permission to build the road. Should the road be torn out, the property would revert to the owner's exclusive use. I would think a reasonable case could be made that the farmer has an absolute right of way across the a public right of way ON HIS PROPERTY. In short, it's the government's responsibility not to interfere with his reasonable use of the rest of his land by building a road without a crossing capable of supporting the tractor.
I am sitting in front of a nice new 40” screen, reading Carry_Okie’s post and my friend, agrees with Carry_Okie.
Oh, I forgot to mention that my friend is a surveyor, and at 89 yaqrs old is likely one of the oldest and most experienced surveyors in Florida. Or perhaps America.
NVDave has posted a series of posts which are an excellent example of why FreeRepublic.com is such a valuable resource.
I will use this thread as an example of how the Internet can make highly technical or legal issues both understandable and readily available to the autodidact.
PS For you Liberals (and we know you are lurking out there) look up the word. Hint: It describes much of education in an earlier and more successful America.
PPS America may be returning to that education modality.
