Rickety bridge

Did my run this morning and stopped to blip at the end during cool down. This bridge leads to an old brickworks site full of interesting nooks and crannies. Didn't go up there as I wasn't wearing wellies! Just slightly in focus is the rusty coloured stream. It is always this colour which I believe is due to the historic works there - but I could be wrong. The path that I run along is an old railway track, you can still see the raised platforms in places.
