Well, I know of one dubious case in Cornwall:
https://www.openstreetmap.org/way/270055625
is an historic ford crossing the West Looe River which is just about
tidal at that point. It was incorrectly mapped as a bridge 
some years ago: I have no idea how that could be so wrong, but then
I have surveyed near there several times, and presumably the "bridge"
was from armchair mapping.

I can just about imagine a local farmer crossing in a large tractor
when the water is very low, but I have seen no sign that there is any
modern use. Streetview seems to have got a bit of the track leading
there: https://goo.gl/maps/9JeA6d6WN7Mbn72V6

Anyway, there can be genuine fords which are tidal, even if this
particular example is disused.
