Google Maps shows that the road ends there. There's a parallel paved road a mile south, which even has signs for the airport. Both routes are about the same length.
Edit: Hang on, Google Maps is using some (at least) five year old imagery in their satellite view, and possibly for their routing. The roads in that area were a bit different then compared to later images from Google Earth, so the dirt road would have been about 0.8 miles shorter. I wonder if this sort of thing accounts for many GPS glitches?
