I will get a friend to make a map of the freeways in the next few days, and then I'll merge it in. As for 'Elizabeth then along the Torrens', it's worded badly, but the route is actually correct! (I'll correct the wording.) It followed the Torrens Gorge, then quickly diverted north just before Modbury, and then made its way to Elizabeth. If you've got Google Earth, it's easy to see where it would have divulged from the O-Bahn route and continued as what McIntyre Road is today.  talk
