Closure of B4386 without notice

I have just found a really nice guy putting up road closure signs on the B4386 in Chirbury. They are closing the road now for potholing – all the way to the Marton turning. Two and a half miles or so.
Fixing potholes fine – closing roads again with no notice is totally unacceptable!.
Did they tell the school transport? Or the Service bus? No of course not.
Were the Clerk and I given even 12 hours’ notice to let people know? Of course not. Diversions here are huge.
I have asked Shropshire Council many, many times to put in proceedures to stop this happening but have not had answers.
Shropshire’s contractors go blithely on not caring how much didruption they cause!
