Franklin Delano Roosevelt Bridge

The Franklin Delano Roosevelt Memorial Bridge is an international bridge which connects the community of Lubec, Maine in the United States with Campobello Island in the Canadian province of New Brunswick across the Lubec Narrows. The decked steel beam bridge is named for Franklin D. Roosevelt, the 32nd President of the United States, who maintained a summer retreat on Campobello Island. A plaque in the middle of the bridge is the easternmost physical marker of the Canada–United States border.The bridge, connecting New Brunswick Route 774 to Maine State Route 189, is Campobello Island's only fixed connection to the mainland of North America; all of the island's transportation connections to the rest of New Brunswick are by seasonal ferry.
