Thanks for the typo check - now maybe you'd want to fix your double reply? 
As already noted and mapped out, all of the east half of Saddle road sits in the inundation zones for Mauna Loa so it would have to be moved many miles to avoid another future genius from questioning why they didn't just place the road outside the lava's reach (using computer predicted descent paths based on digital elevation models several decades before either were invented, at many times the cost, and breaking century old property rights in the process). The western extent of Saddle was realigned in parts largely through other state land which is obviously much simpler.
Eveything seems easy when you don't bother to know anything about the situation. I might as easily say how hard can it be to build a telescope on a mountain where it's been done several times before? Recent history shows it's apparently quite hard - maybe even impossible.
