The Castello Branco Highway (SP-280), which connects the city of São Paulo to the interior of the state of São Paulo, is facing significant traffic congestion totaling 50 kilometers as of early afternoon on Saturday (14). This heavy traffic is primarily attributed to the influx of vehicles as many people embark on trips for the Carnaval celebrations. The congestion is particularly pronounced and stretches from kilometer markers 19 to 43, affecting the municipalities of Barueri and Santana de Parnaíba, as well as additional slow zones at kilometers 48 to 54 near Araçariguama.

According to data from CCR Via Oeste, the company responsible for managing the highway, the most significant bottlenecks include 24 kilometers of slow-moving traffic, with additional delays logged from kilometer markers 20 to 24 and 18 to 37. These slow zones are also notable for impacting the commuting experience through Barueri, Santana de Parnaíba, and Itapevi. Such extensive traffic conditions highlight the challenges of travel during peak holiday seasons like Carnaval.

The congestion on the Castello Branco Highway serves as a reminder of the increased road use during major holiday periods in Brazil, illustrating the diverse travel demands that coincide with festive events. While the highway is a crucial link for travelers heading to various destinations, the traffic implications show a need for ongoing infrastructure and management strategies aimed at facilitating smoother travel during peak times.
