Explanation :At one time Yonge Street(Toronto-Canada) held the Guinness Book of World Records for the Longest Street in the World. There is some controversy regarding this now, Guinness has removed it from the record books, but Toronto clings to the name. Seems at one time Yonge St was part of a larger system called Highway Due to changes in the way the road system was run, it was disassociated from Highway. However, Torontonians still claim it’s all the same road.
It now lists the longest motorable road in the world. The longest motorable road in the world is the Pan-American Highway that covers 18 different countries and is connected to three others, spanning the two continents of North and South America. The Pan-American Highway stretches for a whopping 48,000 km and crosses a diverse variety of terrains and climates.

The 100 km gap in the Pan-American Highway is called the Darien Gap. The gap exists between Central America and South America with the two countries involved being Panama and Columbia. The Darien Gap is entirely a stretch of marshland.
