Why NO Bridge Crosses The Amazon

追加: 2026-05-05

[00:00:00]Can you believe that one of the longest rivers in the world, flowing through multiple countries, does not have a single bridge across it? The Amazon River is over 6,000 km long.

[00:00:11]If you want to cross to the other side, your only option is to take a boat.

[00:00:16]The biggest reason comes from the harsh changes in nature. During the dry season, the river is only about 5 km wide.

[00:00:24]However, when the rainy season arrives, the water rises and expands up to 50 km.

[00:00:30]The banks, which are soft mud, instantly turn into a giant swamp. Building bridge foundations on constantly deforming and flooded land is an insurmountable technical challenge.

[00:00:42]Furthermore, the population density along this massive basin is extremely low.

[00:00:48]The transportation network here relies mainly on waterway ferries.

[00:00:52]The demand for overland travel is simply not high enough to spend billions of dollars on a high-risk project.

[00:00:59]Therefore, this giant water monster remains free, untamed, and completely unbounded.
