There is a bus service which transports passengers from the city of Bonfim to the city of Boa Vista in the state of Roraima of Brazil.
The bus leaves the city of Bonfim at three different times of the day: 10:00 A.M., 12:30 noon and 3:30 p.m.
A ticket from Bonfim to Boa Vista costs around 20 reals.
The buses are big and air-conditioned and they can be relaxing to travel in. I have never heard reports of any accidents with the buses running from Bonfim to Boa Vista.
