Pan-American Highway
The Pan-American Highway is a network of roads stretching across the American continents and measuring about in total length. Except for a rainforest break of approximately , called the Darién Gap, the roads link almost all of the Pacific coastal countries of the Americas in a connected highway system. According to "Guinness World Records", the Pan-American Highway is the world's longest "motorable road". However, because of the Darién Gap, it is not possible to cross between South America and Central America with conventional highway vehicles. Without an all-terrain vehicle, it is necessary to circumnavigate this terrestrial stretch by sea.
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.
