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.
Ryfast
When the last section was drilled on 26 October 2017, Ryfast became the longest undersea road tunnel in the world, with its 14.3km length greater than the Tokyo Bay Tunnel in Japan (9583m.) and the Shanghai Yangtze River Tunnel (8950m.) in China.
