I was about to say I was surprised you hadn't but then noticed the lack of a c on the end of your username.
Unless I'm mistaken that's the Leuchold Gate. It's entirely tarmac (bar a couple of cattle grids) and mostly downhill. The one nasty bit is the sharp left turn just after half way through the route. The road is in a bit of a cutting so you can't see what's round the bend until you are. It's also generally quite gravelly at that point.
In the other direction the hill is long but not too steep (relative to others in the estate).
Well worth the diversion from the B924 if you've never done it before.
