The above postcode is for the pub in Wilcot village, NOT the actual portage.
From Honey Street Bridge, retrace your route back to the village of Alton Barnes.
In village, immediately after the junction you came in from earlier, turn right signed to Wilcot/Pewsey.
Drive through village of Alton Priors and stay on same road until you come to Wilcot Bridge.
The bridge is BEFORE the village of Wilcot but the postcode of the pub in the village is SN9 5NN. (I do not know if this is open for business early on Good Friday morning - if you want to ring to find out the tel.no. is 01672 562289)
