It borders the Catumbi, Estácio, Praça da Bandeira and Tijuca neighborhoods.
This river is currently canalized and completely degraded, and empties into Guanabara Bay.
The name Rio Comprido means Long River.
In the 17th century the Rio Comprido valley produced sugarcane, flowed off by a warehouse in embarkations which conducted it to the bay.
When the Paulo de Frontin viaduct was opened, it created access to the Rebouças tunnel and to the city's southern zone, turning Rio Comprido into a passageway neighborhood, currently surrounded by lower income communities, such as Turano, Fogueteiro, Querosene, Fallet, Coroa, São Carlos and Mineira, which suffer from violence and social exclusion.
