I have been in further email conversation with Andrew Stevenson (councillor) on the topic. The legal status of the urban clearway appears still to be in some doubt and whist the bollards have had some impact on parking of HGVs ( albeit moving the problem) it has had zero impact on the main problem of cars queueing onto the roundabout.
Andrew asked if I am supportive of a public meeting at County hall where we (the public) will be able to put our case to both the council and Police. Once I have a date I will post it on here. I would welcome your support at the meeting to show the communities unhappiness at the lack of progress in this safety issue. Thank you Nigel
