"Maine State Route 6 State Route 6 (SR 6) is part of Maine's system of numbered state highways, running from west to east across the state. Its western terminus is at the Canada–United States border near Sandy Bay (a terminus it shares with U.S. Route 201), where it connects to Quebec Route 173. Its eastern terminus is at the Canada-US border in Vanceboro, where it connects to New Brunswick Route 4. SR 6 is the only highway in Maine to terminate at the Canadian border at both ends.

None of the four Kentucky counties that border Missouri has any direct highway connection with Missouri. Kentucky and Missouri are the only two U.S. states to border each other, even across a major river, without a direct highway connection between them.

At various times, national borders with territories formerly controlled by other countries (British North America, New France, New Spain including Spanish Florida, and Russian America) became institutionalized as the borders of U.S. states. In the West, relatively arbitrary straight lines following latitude and longitude often prevail, due to the sparseness of settlement west of the Mississippi River.
