Arara River is a river of Amazonas state in north-western Brazil. It is a tributary of the Unini River, which stems from Negro River. [1] This is not to be confused with Arara River in the Acre state of western Brazil.
Amazonas is a state of Brazil, located in the North Region in the north-western corner of the country. It is the largest Brazilian state by area and the ninth-largest country subdivision in the world. It is the largest country subdivision in South America, being greater than the areas of Chile, Paraguay, and Uruguay combined. Mostly located in the Southern Hemisphere, Amazonas is the third-largest country subdivision in the Southern Hemisphere after the Australian states of Western Australia and Queensland. Located entirely in the Western Hemisphere, it is the fourth-largest country subdivision in the Western Hemisphere after Greenland, Nunavut, and Alaska. If independent, Amazonas could become the sixteenth-largest country in the world, slightly larger than Mongolia. Neighbouring states are Roraima, Pará, Mato Grosso, Rondônia, and Acre. It also borders the nations of Peru, Colombia and Venezuela. This includes the Departments of Amazonas, Vaupés and Guainía in Colombia, as well as the Amazonas state in Venezuela, and the Loreto Region in Peru.
The Rio Negro, or Guainía as it is known in its upper part, is the largest left tributary of the Amazon River, the largest blackwater river in the world, and one of the world's ten largest rivers by average discharge.

It spans the Rio Negro just before its confluence with the Amazon River, and is the only major bridge across the Amazon or any tributary in the Amazon basin.
