Numerous animal species can be found in the world's second-largest river, the Amazon.  No country has ever tried to construct a bridge across the river, despite the fact that it flows through multiple nations.
 
The river is home to 60 species of piranha, 100 kinds of electric fish, and the greatest population of river dolphins. Up to nine nations are traversed by the amazon, including Brazil, Ecuador, Peru, and Colombia. It is noteworthy because more than 30 million people reside in the river's basin, which spans almost 40% of South America. Astonishingly, no bridge has been constructed over the river thus far in such a scenario.


No Need For A Bridge On Amazon
In an interview with "Live Science," Walter Kaufmann, the head of structural engineering at the swiss Federal Institute of technology (ETH) Zurich, discussed the lack of a bridge across the river.  According to him, the amazon river did not require a bridge.
 
There are very few people living in the region where the amazon runs, according to Kaufman.  Furthermore, there aren't many main highways that link any bridges.  In addition, there is no particular need to construct a bridge across the amazon because there are sufficient boats and ferries to transport people and products to the towns and cities along the river.


Constructing A Bridge On Amazon
According to Kaufman, building a bridge across the amazon poses a number of logistical and technological difficulties.  He pointed out that because of the soft terrain and large marshes, the river's conditions are not suitable for building bridges.  The bridge would therefore need a deep base, which would require a large financial outlay.
 
 Because of the regular variations in water depth and the ever-changing weather, constructing a bridge across a river can be challenging.  Kaufman claims that the river's water level varies throughout the year and is not continuous.  It is significantly more challenging to build a bridge here in such a circumstance.
