Highway
Major highways are often named and numbered by the governments that typically develop and maintain them. Australia's Highway 1 is the longest national highway in the world at over and runs almost the entire way around the continent. China has the world's largest network of highways followed closely by the United States of America. Some highways, like the Pan-American Highway or the European routes, span multiple countries. Some major highway routes include ferry services, such as U.S. Route 10, which crosses Lake Michigan.
Yonge Street
Yonge Street was formerly a part of Highway 11, which led to claims that Yonge Street was the longest street in the world. Running (mostly) concurrent with Yonge as far north as Barrie, then continuing beyond through central and northern Ontario to the Ontario-Minnesota border at Rainy River, the highway was over long. But Yonge Street could only be called the longest street in the world if were fully synonymous with Highway 11, which has never been the case.
