Highway M-185 in the U.S. state of Michigan, is the safest road in America because it is the only state highway in the nation where motor vehicles are banned. The restriction dates back to 1898, and since the ban, just a handful of vehicles have driven on the asphalt, other than the city's emergency vehicles. M-185 is peculiar for another reason — it leads to nowhere, because it’s circular and lies entirely on an island. And because it lies entirely on an island, it doesn’t connect to any other highways. No wonder, the M-185 isn’t listed on the National Highway System, which is an index of strategic highways and roads within the US that’s important to the country's economy, defense, and mobility. But one does wonder, why M-185 is called a highway at all?
