Regarding the proposed call for a roundabout at the Peppermint Junction, consider other solutions such as the ones in place at Swineshead Bridge, plus amendments,before breaking into the road.
1 – Imposed speed restriction either side of junction;
2 – Install high-risk accident signage;
3 – Paint red rumble strips on approach with with full red road markings in immediate area with speed markings.
4 – Install speed reactive visual camera on approach followed up with penalty camera should anyone choose to ignore all the information they have just driven through.
PS: I cover most roads around the county daily and I detest speed cameras. However, in certain locations they do a reasonable job in slowing traffic to allow entry onto the road
