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.
Queensway Tunnel
At the time of its opening it was the longest road tunnel in the world, a title it held for 14 years until the opening of the Vielha Tunnel in Catalonia, Spain in 1948, though it remained the longest underwater tunnel as of 1955. The tunnel, which cost a total of £8 million, was opened on 18 July 1934 by King George V; the opening ceremony was watched by 200,000 people.
