In reply to Ferret:
I passed that way in May 2014, and as I recall we passed dryshod over a very substantial recently constructed vehicle bridge. A bridge is shown on my 2011 OS 1:50K Sheet 42. But I suppose, given the dismaying recent frequency of downpours and flash floods, it may just conceivably have been carried off since then ... somebody with more recent experience may be able to confirm.
