bus line 39 follows a 'circular' route, meaning that after the final stop on rua general cristóvão barcelos at prainha de piratininga, it continues onto a different route along avenida almirante tamandaré to return to the original stop at the bus terminal rodoviário joão goulart.   

travelers must exit the bus at the final stop and pay the fare one more time to continue along the second part of the route via avenida almirante tamandaré, if they wish to continue along piratininga beach, praia do sossego, and praia de camboinhas.
