A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it.

South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere. It can also be described as the southern subregion of a single continent called America. South America relies less on the export of both manufactured goods and natural resources than the world average; merchandise exports from the continent were 16% of GDP on an exchange rate basis, compared to 25% for the world as a whole. Brazil (the seventh largest economy in the world and the largest in South America) leads in terms of merchandise exports at $251 billion, followed by Venezuela at $93 billion, Chile at $86 billion, and Argentina at $84 billion. The main agrarian crops are export crops, such as soy and wheat. The production of staple foods such as vegetables, corn or beans is large, but focused on domestic consumption. Livestock raising for meat exports is important in Argentina, Paraguay, Uruguay and Colombia. In tropical regions the most important crops are coffee, cocoa and bananas, mainly in Brazil, Colombia and Ecuador. Traditionally, the countries producing sugar for export are Peru, Guyana and Suriname, and in Brazil, sugar cane is also used to make ethanol. On the coast of Peru, northeast and south of Brazil, cotton is grown. 50. 5% of South America's land surface is covered by forest, but timber industries are small and directed to domestic markets. The main industries are: electronics, textiles, food, automotive, metallurgy, aviation, naval, clothing, beverage, steel, tobacco, timber, chemical, among others. Exports reach almost US$400 billion annually, with Brazil accounting for half of this.
