Wessex Water have announced an emergency closure of Stanmoor Rd, north of Cutts, to mend a leak, from 9th May, “between the hours of 00:00 – 23:59″. This suggests that you might be able to nip through a minute before midnight, but I think they mean it will be closed 24h hours a day. The duration from 9 to 13 May is only an estimate. You’d hope it would be shorter. The official deviation map is shown below, though alternative routes might make more sense depending on where you are coming from and going to.
