Hi again. 
This is the millwheel: https://www.openstreetmap.org/node/260995057
And this is the bridge that I added after your original note: https://www.openstreetmap.org/way/1165455539
Your Organic Maps OSM snapshot is outdated, maybe that's why you don't see the bridge yet. The millwheel isn't displayed on the (standard) OSM map.
