Went here last weekend travelling south from Sydney. The roadworks are still ongoing - no right hand turn yet. What I did is travel a little further down the road where there is a left hand turn off the highway. You can do a quick U-turn and then wait there to turn right back onto the highway. The vision is good, and anyway, with the Tesla's acceleration there's no issue rejoining the highway. Then it's a simple left turn into the winery. I ended up buying four bottles of wine after a tasting while the car charged. Had to move it part way through the tasting to avoid idle fees - first world problems.
