Accident black spot.
Discussion
Anyone on here familiar with the Thistly Cross roundabout near Dunbar?
It’s been an accident black spot for years with cars heading South mounting the middle of the roundabout. Rumble strips and flashing signs have lowered the rate a bit but it’s still a regular occurrence. Bear are going to do some work on it but I’m not sure what else they can do.
I reckon it’s because it’s in a dip and somehow there an illusion that the road carries straight on. But of course being local it’s difficult to imagine it through a strangers eyes.
Not a regular down that far and the signage and rumble strips start a fair bit back. I can only assume people are running on auto pilot from as far back as The Jewel and not switching on the road becoming a roundabout. Kinda get it - not difficult to slip into a dual/motorway rhythm.
Could be redeveloped into a proper junction like the many before it but they'll never spend the money.

Looking at this junction on Google Maps it’s noticeable that warning signs approaching the roundabout on the A1 are inconsistent. From the east each of the 100m countdown boards also has a roundabout warning sign attached, which I should imagine would assist the less observant drivers. Approaching from the west (the direction the OP states is a black spot), drivers are alerted by two roundabout warning signs with plates reinforcing the hazard - ‘reduce speed now’, but without additional warning signs on each countdown marker.
If the east approach isn’t as hazardous, then this suggests that more roundabout warning signs help the situation.
For consistency on both approaches, and using information that the eastern approach is safer than that from the west (the OP only states that the western approach is a black spot) installing roundabout warning signs with ‘reduce speed now’ plates near the original direction plaque signs on the eastern approach, and adding roundabout warning signs on each of the countdown markers on the western approach. It is becoming standard practice when supported by data to reduce speed limits on the approach to roundabouts on NSL roads, and a reduction to 40mph, or more likely 30 with suitably sized gateway signs 200m or so before the roundabout might be advantageous.
