El Marco (World's Shortest International Bridge), Várzea Grande Village - El Marco Village, The Portugal–Spain Border

El Marco is the World's shortest international  bridge connects the  Portuguese  village of Várzea Grande (Arronches municipality)  with the Spanish village of El Marco (La Codosera municipality). It is a wooden bridge  with measures only 10.4 feet long (3.2 meters), this bridge spans two countries. You can effectively cross from one country to another in a single hop.

The Portugal–Spain border is referred to as "The Stripe". It is one of the oldest borders in the world. The current demarcation is almost identical to that defined in 1297 by the Treaty of Alcañices. The Portugal–Spain border is 1,214 km (754 mi) long, and is the longest uninterrupted border within the European Union. The border is not defined for 18 km (11 mi) between the Caia river and Ribeira de Cuncos, because of the disputed status of Olivenza/Olivença, which has been disputed between the two countries for two hundred years. A microstate existed previously on the border called Couto Misto.

Funded by the European Union, the tiny wooden piece of infrastructure was built in the first decade of the 21st century by laborers from both the Spain and Portugal sides of the stream. The little bridge links the Spanish municipality of La Codosera with the Portuguese Arronches. Given its petite size, the bridge is largely for pedestrians, not automobiles, though two-wheeled vehicles may use it as well.

The title of World’s Shortest International Bridge is often erroneously awarded to the bridge that spans the United States-Canada border between Zavikon Island and another tiny island that happens to fall in USA territory. The Portugal-Spain bridge is at least 13 feet (4 meters) shorter than its North American counterpart.
