Isn't that pretty much an acceptance that the current limit is too low for the condition of the road in question?

The reason why it's a 50mph stretch at this point is due to the road noise as a consequence of the road construction in a built-up environment - not the traditional "condition of road".

A single camera at the far end of the stretch, well beyond most residencies, isn't exactly helpful though.

The best "speed" solution for the A34 from Newbury to the M40 (other than being rebuilt as a 6-lane with hard shoulder motorway) would be something similar to that on the M42 at Birmingham - overhead variable speed signs with average speed cameras."
