I've had a stab at restoring it. When @CharlieH22 dragged the end of the bridge onto the running track, merging the node deleted the newer node, n378212139. Luckily, the running track was mapped before the bridge, so I've undeleted this node.

The path from the bridge was also glued to the London LOOP path, with @CharlieH22 creating n11841258383. I have deleted this node.

There is probably a better way to do this using archived extracts from planet.osm or using Overpass Turbo's attic data, but hopefully I've fixed it in https://www.openstreetmap.org/changeset/151139452

When I get a chance, I'll do a run along that section of the London LOOP and check it my GNSS trace against the map. I'm injured, so this may be a few weeks.
