Lubec/Campobello Bridge, Maine

The easternmost physical structure bisected by the international boundary between the US and Canada is the Franklin Delano Roosevelt Bridge, which connects the town of Lubec, Maine, and Campobello Island, part of New Brunswick, Canada. Campobello is a kind of an exclave of Canada, an island connected by land only to the USA, by this bridge. The US President, Franklin Roosevelt, had a vacation home on the island, which is preserved and visitable. There is a customs and immigration port of entry building on either side of the bridge, the easternmost of the 24 official border crossing points in the state, and the 115 or so along the line between the east and west coasts.
