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.
A6 autoroute
The A6, also known as the Autoroute du Soleil, "Motorway of the Sun", (along with the A7), is an Autoroute in France, linking Paris to Lyon. The motorway starts at Paris's Porte d'Orléans and Porte d'Italie with two branches, numbered A6a and A6b respectively, that join south of Paris. The motorway is favoured by holidaymakers as it is the main link to the South of France and the French Riviera. At 455km long it is France's third longest autoroute after the A10 autoroute and the A4 autoroute.
