This was a mis-click on my phone, but I am having trouble finding a way to delete it in the map editor on my computer. When I try right-clicking on it, nothing happens. When I use the keyboard shortcut to delete it, nothing happens. This is actually the other side of the bridge that is marked nearby.

This building is now a Domino's Pizza. Typing in the address (4845 N 90th Street) gives a location on the opposide side of the street.
