In the wrexham.com story about this incident it states that diversions were put in place. This was not true the roads were closed with alternatives advised. Gresford roundabout just had police closed signs llay new road by the bridge had a council worker with road closed signs and the same with the Wrexham Rouindabout. There were no advance warnings either.
Hope the faller survives and my thoughts are with his/her family.
