This road is absolutely right-turn restricted. This whole road from roundabout to roundabout has no right turning because it's a dual carriageway.

I think I saw a right turn lane somewhere down this road? but I wouldn't chance it at national speed limit speeds..   anyway, I've surveyed this road and it's the access road/driveway to the buildings near the roundabout. 
There's a closed gate and the road in between the carriageway I suppose is for the people on that private road to make a (dangerous) right turn from their driveway. 

I've set the road to private hopefully not allowing a satnav to indicate someone make a right turn here but that's the most that can be done for it.  

This note should probably be resolved now.
