Do any bridges cross the Amazon River?
Most of the time, the crossing can be done by a ferry, so there is no need to build a bridge. The Manaus Iranduba Bridge linking the cities of Manaus and Iranduba spans the Rio Negro (a tributary of the Amazon). The river is the main route of traffic in the region.
No bridge crosses the river along its entire length. The Amazon and its tributaries flow through the countries of Peru, Bolivia, Venezuela, Colombia, Ecuador, and Brazil before emptying into the Atlantic Ocean 6, 437 kilometers (4,000 miles) from the Amazon's headwaters high in the Andes mountains of Peru.
- The basin is 2.7 million square miles while the Amazon covers 2.1 million square miles of it. If the Amazon rainforest was a country, it would rank 9th in size. The nine nations that have the Amazon rainforest in their borders are: Brazil, Peru, Colombia, Venezuela, Ecuador, Bolivia, Guyana, Suriname and French Guiana.
- A leading theory holds that the Amazon once flowed west, perhaps as part of a proto-Congo river system, from the interior of present day Africa when the continents were joined as part of Gondwanaland. Fifteen million years ago, the Andes were formed by the collision of the South American plate with the Nazca plate.
- That is more than 150 acres lost every minute of every day, and 78 million acres lost every year! More than 20 percent of the Amazon rainforest is already gone, and much more is severely threatened as the destruction continues. It is estimated that the Amazon alone is vanishing at a rate of 20,000 square miles a year.
Although it now empties into the Atlantic Ocean, the Amazon once flowed into the Pacific! The uplift of the Andes Mountains about 65 million years ago in a geological event called the Laramide Revolution cut the flow to the Pacific, and forced the Amazon River to flow eastward.
- Off the Atlantic seaboard of the United States, the Gulf Stream flows at a rate nearly 300 times faster than the typical flow of the Amazon River. The velocity of the current is fastest near the surface, with the maximum speed typically about 5.6 miles per hour (nine kilometers per hour).
- Amazon River. Greatest River. The Amazon is the greatest river in the world by so many measures; the volume of water it carries to the sea (approximately 20% of all the freshwater discharge into the oceans), the area of land that drains into it, and its length and width.
- The total length of the Amazon River from its source springs in the Andes (taking the Ucayali River as the continuation of the main river into the Andes), is estimated at 6518 km ( ~4075 miles) (not including all river bends, and measuring the short distance around Marajó Island in the mouth of the Amazon).
