It's really too bad that a barrier couldn't be built to prevent this flow from oozing across a major highway.
That barrier would have to be big, long, tall. The topography along that stretch of the saddle is pretty flat, and the lava itself viscous enough that it isn't just running around. Instead, as it encounters barriers it's going to pile up and climb over them too.
I'm imagining a large perched pond, a 'secondary' lava lake, forming before the flows get over to the Mauna Kea side. In that case where the lava goes from there can be in any direction. Whichever side of the levies that form is breached first.
And still, if I was wagering, I'd go with kalianna, but move the line a bit. She'll stop once she blocks the Mauna Kea access road.
