Welcome to OpenStreetMap.

Please keep your changesets local, as a changeset spanning two continents makes it hard to review.

I note that you have not given a source for your import. This is potentially a problem, as there is no way to determine if your source(s) are compatible with OpenStreetMap.

Why did you remove the highway=trunk tag from the A299 Chelsfield Tunnel in Kent, UK? This has nothing to do with oysters and would break routing, a real world use of OSM data. I have repaired this in https://www.openstreetmap.org/changeset/146069283

The non-existent park you created as a POI has also been removed.
