After looking it over it is possible that the road will be hit by the flow, but also possible that it won't. Previous flow paths from google maps with satellite view show how some have curved either East or West of the current fall line. That youtube video is a very cool piece of work.
No worries - there is so much data and so many visualizations out there currently that you can review several interesting takes in the time it would take to roll your own.
The flat area by Pu'u Huluhulu is pretty open and paths both to the west and the east appear possible, but on the diversion topic, the 1843 flow seems to sit somewhat higher up so we may see it help divert the current flow back to the east paths if it can't overtop it or sneak around the edge just before Saddle. The steepest descent paths to the west stay pretty much south of Saddle till its termination at 190 so if you wanted the best chance to preserve the road it seems you'd be hoping for that westerly turn (and the flow would cut through PTA, so bonus?
) but it would impact the newly announced lava viewing route along "the slice".
