Jakeroo, that's right, bridleways are for horses but people are allowed to walk as well as long as they get out of the way if they are coming.
As my last old sign went down so well here's one more, Streetview began with only London for 50 miles around and when it went national a year later also filled in a few bits within London it had missed originally. One amazing sign (it had a red circle on top, they went away first and only my second sighting) was found within days, and last night I found this one only a few miles from where I live, also the only one known to survive online.
The reason it's dark as I found it at 12.35am and had taken it by 1am. Besides less traffic I wasn't prepared to wait for one that good and round the corner. The signs look the same anyway with the flash unless on a bridge like the day before that.

For those not familiar, this font and style was replaced in 1964 for lower case or worse still pictograms on their own borrowed from the continent, and raised lettering was also abandoned despite lasting a century if looked after. False economy as always.
