Coming from the North I drove down the road to where it stops about 200 yards short of Journeys End. It isn't cement yet but dump truck and bulldozer traffic have it built up and packed down so its drive-able....unless it rains.
These guys seem to work on Sundays and after dark so I would expect to be able to drive to work by next week.
