I crossed those two tidal roads years ago in my MG Metro. The water was almost a foot deep, and with the benefit of hindsight I should have turned round.
I didn't realise there were two, so having got across the first one OK, the second one looked impassable. So I knocked on the door of the cottage which stands adjacent, and the owner took a measured look at the poles, and told me it would be OK.
It was OK.
My mother wasn't impressed.
