Together with the Raposo Tavares Highway (SP-270), it links the capital of São Paulo to the western interior of the state, known as the Castelo-Raposo System. It also allows access to the Midwest and North regions of Brazil and neighboring countries (Bolivia and Peru) by interconnecting with the Marechal Rondon Highway (SP-300), made by the João Hypólito Martins Highway (SP-209), which connects the Castle to the city of Botucatu. The Castle is also a route to the southern region of the country (western Paraná) and countries like Paraguay and Argentina.
The concessionaire CCR ViaOeste estimates that around 100 thousand vehicles will travel through the Castelo-Raposo System on a daily basis. The operation is monitored by the 78 cameras linked to the Concessionary's Operational Control Center (CCO) and also by the Integrated Control Center (CCI) of Artesp.1
