Cruised under Bridge 6 this morning.
Just want to mention there are 8 or 10 pipes (white hard plastic 2 inch drain pipe type) sticking out about 3 to 5 inches from the brickwork along the roof, and sides. It would be easy to catch them, and pick up scratches, both on your boat and on your head! This morning was lovely and bright and they were very visible, but on a dull day, and concentrating on a boat coming towards you or something, you could miss seeing them, and that could be nasty. I'm sure if these were on the roadway, there'd be red flags dangling from them.
I can only think the pipes have been added to remove moisture.... (don't take my word for it though).
Having mentioned the pipes, I feel lots better now! Ashby bridges are 'snug' at the best of times.
