Br 116
In short
The BR-116 is the longest fully paved highway in Brazil, stretching 4,542 km from Fortaleza in the north to Jaguarão in the south.
In plain words
It is a massive road that runs almost the entire length of the country. It connects the northeast region to the border with Uruguay. Because it is all paved, it is a vital route for moving goods and people.
A simple example
A truck driver can travel from the coastal city of Fortaleza all the way to the southern border without ever leaving a paved road.
Why it matters
It serves as a backbone for Brazil's economy by linking major cities and trade hubs. Its length and paved status make it essential for national logistics.
Easy to mix up
Do not confuse it with the BR-101, which is another major highway running along the Brazilian coast.
