Good spot, have removed the bridge tag

Sorry I didn't add a changeset comment The source is OS StreetView, and also the NLS's 1888 OS Maps, among a few others, however I noticed I put it in wrong, and should be Smallfield Ridge, not Edge. I have already corrected it.

Sorry this was my mistake - human error. I shall endeavour to be more careful in the future.

Right folks, this is all my fault. The 'natural=yes' is my way of checking what I have and havent done in JOSM. I must have accidentally uploaded it - i've recently had a number of JOSM related issues, but hopefully now all resolved. It indeed needs reverting, though I am unsure how to do this.
Apologies for the trouble - I'll make sure to be more careful in the future!
