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.
Yiwu–Madrid railway line
The Yiwu - Madrid Railway line is a railway route taken by container trains from the Chinese city of Yiwu to the Spanish city of Madrid, a distance of approximately , and the longest in the world. The Trans-Siberian Railway was previously the longest. It is one of several routes used by long distance freight trains on the "New Eurasian Land Bridge". (Other city pairs connected by regular freight trains running between China and Europe include e.g. Lianyungang and Rotterdam, or Yiwu and Warsaw; as of 2016, at least 12 Chinese cities and 9 European ones were connected by similar trains.)
