The Old Serra of Tamoios Highway has been completely blocked for more than 20 hours as of Monday afternoon, impacting the region of Caraguatatuba on São Paulo's North Coast. The closure began late Sunday evening at around 8:45 PM due to significant rainfall that resulted in five points of land and rock slides along the highway. This highway serves as one of the main access routes to the North Coast, and the concessionaire managing the road has prioritized user safety in announcing the closure.

According to the concessionaire, the highway will remain closed on Monday, and there are no indications of when it might be reopened. The teams are actively monitoring rainfall accumulation, soil conditions, and the weather forecast as they assess safety for future travel. Meanwhile, traffic is being managed through a convoy system on the adjacent Nova Serra roadway, operating under a stop-and-go pattern to help alleviate congestion caused by the main roadway's closure.

This situation highlights the vulnerabilities of road infrastructure in the face of extreme weather conditions, particularly in regions sensitive to heavy rainfall. Local authorities and transport officials will need to continue assessing the impacts of such weather events and the preparedness of the roadway systems to manage future incidents, ensuring safety for residents and travelers in the area.
