If anyone is planning to activate WB-003 and WB-005 in the near future, there are a couple of problems with vehicular access which I encountered on 2 March.
If you are approaching Bridges from the south, the road is completely closed at Walkmill due to bridge repairs, necessitating a long diversion via Whitcot, Wentnor and over the hills to rejoin the “main” road just south of Bridges.
At the bottom of the road leading from Ratlinghope to the top of the Long Mynd, there is a red sign saying “Road Closed due to snow and ice”. I chose to ignore the notice and drove up the hill anyway! In fact there was no snow and ice and the road was perfectly passable. D’oh!
