Somerset Bridge -- Smallest Drawbridge in the World

From http://www.bermudatourism.com/default.asp?page=what_to_do.html:

One of the first three bridges built in Bermuda in the 17th Century, Somerset Bridge connects the mainland with Somerset Island. Charming Ely's Harbour is to the west and the Great Sound to the east. This picturesque bridge is said to be the smallest drawbridge in the world. The central plank can be raised to allow the mast of a sailboat through.
