I saw your note this morning before going cycling and rode over there to ground survey this.

The northern and middle legs of construction visible in the latest Bing imagery are paved to completed turning circles.  The southern leg, which I've marked as highway=construction has been graveled, but not yet paved.  Based on the signage, it appears that this leg will also be Tracker Lane, but it is possible that there will be another sign on the south side of the intersection not posted yet.
