Yeah interesting one that I worried about for a while. There is a no left and no right turn into it from Princes Hwy and only a reserve (no driveways) back to the next intersection north. One could only U or 3 pt turn if it was wide enough. Part of my decision was also about the fog (white) line being continuous. Sixmaps/DCS was quite old at that point and the fogline was dotted then.

Had to do a head swivel to check the northbound turn restriction as the left/rear camera only cuts in below 38kph.

Short answer is there will never really be any northbound traffic on that section of Centenary Drive. Dunno if it would be legislated one way or not though. Eurobodalla Shire was also against RMS restricting the turn off from Princes with a guardrail back in 2019 https://www.beagleweekly.com.au/post/2019/06/26/council-says-no-to-proposed-closure-of-access-from-princes-highway-into-centenary-drive-a

The competition also has the rest of the road one way on the other side of the bay too. I wasn't there of course.

Your call?
