I see you added a connecting way from the bridge to 40th, but didn't add that way to the Riverlake Greenway bike route relation. The relation already routed over the footway and small chunk of 2nd Ave (essentially the other two sides of the triangle formed by your new way). I think either way could work, but probably would make sense to do one or the other. If you're not sure, it might be worth asking some other local users who edit bike infrastucture (like Jordan Leick?) or on the OSM US Slack. Happy mapping!
