This bridge looks really calm but when you drive over it you can't see the other side, it frightened the life out of me when as a newbie in the countryside I had to drive over it in the dark!
Thank you @macromover@ithinkithunk@hermann@ellida for your kind comments. Jan it's near Wastwater in the Lake District, Graham as you go from Gosforth to Eskdale just before the hamlet of Santon there is a left hand turn down a track (opposite Sorrowstones Farm), it's down there bearing left.
