Why was the trans-amazonian highway build?

The Trans-Amazonian Highway was built primarily to promote regional development and integrate the remote Amazon rainforest into Brazil's economy. Initiated in the 1970s during Brazil's military regime, it aimed to facilitate the movement of people and goods, encourage settlement in the interior, and exploit Natural Resources. However, it also led to significant environmental degradation and displacement of indigenous communities, raising concerns about its long-term impacts.
