tombolo

tombolo (TOM-buh-loh) - n., a sand bar that connects an island to the mainland.


Or to another island -- the word isn't picky. Sometimes it's a shingle bar, if that's what's available to the wave action. From Italian, from Latin tumulus, mound. A tombolo connecting a small islet to Shōdo Island, Japan.
