If there *really* is nothing, you can select the object that represents the way that isn't really there and hit the "del" (maybe "entf") button on your keyboard.

Please only delete elements that are really not there (anymore). If, for example, a building just got razed and the aerial image still shows the building, don't delete it. Also, don't delete a shop when it's closed. Set it to vacant.

If you have questions, please ask. Either me directly or the community at c.osm.org

Cheers
