By a quirk of fate, in early 86 I "owned" the Stanley - MPA road for about 24 hours between taking it over from the contractor and handing it to PSA and FI Govt. It was planned to be tarmac all the way but to save money some of it was rolled stone not blacktop. Also when it opened speed limit was 60mph. Within days a young R Sigs lad went from blacktop to gravel at some speed in a SWB L-R , spun and rolled and sadly was killed. Speed limit reduced to 40mph. Has all of it been blacktopped yet?
