Page 123 of this carry-with-you London atlas ("the definitive London atlas") shows a footbridge on the west side of the Cannon Street rail bridge, labeled Jubilee Footbridge.
On page 120 it calls the Golden Jubilee Footbridges the Hungerford Footbridges. (I once myself saw a sign there that called them that; but that funky painted sign has been replaced with an engraved plaque.)
I have never been aware of a footbridge alongside the Cannon Street rail bridge. It doesn't show up on any of my other maps. Did I miss it?
Can you help me sort this out?
