Motorists encountered extensive queues on the main highways leading to the São Paulo coast as holiday travel intensified ahead of New Year 2026. State traffic authorities implemented Operation Descida (7×3) on the morning of Tuesday 30 December to manage the surge, which is scheduled to remain in effect until 20:00 on Wednesday.
The traffic scheme reallocates lanes to favour vehicles travelling downhill towards the coast. During the operation, traffic towards the coast uses the north and south lanes of the Rodovia Anchieta and the south lane of the Rodovia dos Imigrantes. The north lane of the Rodovia dos Imigrantes remains reserved for vehicles ascending the Serra do Mar.
Officials said the measure aims to improve flow and reduce the standing time of cars on the approach to coastal destinations, where demand typically spikes at the end of the year. Despite the lane changes, drivers reported long queues at several points, with delays compounded by the volume of vehicles and the usual holiday travel patterns.
São Paulo New Year traffic: what drivers should expect
Commuters and holidaymakers should expect slower speeds and intermittent stop-start conditions on the stretch between the capital and coastal resorts. Traffic control teams are positioned along the routes to monitor conditions and direct motorists. Roadside assistance and emergency services are on alert to respond to incidents that might further disrupt flow.
Authorities advised drivers to check real-time traffic updates before setting out, to allow extra travel time and to avoid peak departure windows where possible. Where alternate routes exist, travellers may consider staggered departure times or public transport options to reduce congestion and improve safety.
Motorists were also reminded of basic safety precautions: keep headlights on during low visibility, maintain safe following distances during heavy traffic, and refrain from using mobile phones while driving. With temporary lane arrangements in place, drivers are urged to follow signage and instructions from traffic officers to avoid fines or accidents.
Local municipalities and highway operators typically coordinate ahead of major holidays to deploy measures like Operation Descida. The objective is to balance safety and mobility, but high demand can still produce significant delays. Visitors unfamiliar with the area should allow for extra time to reach hotels and holiday properties.
For commuters returning to the capital after the celebrations, the reverse flow will be managed according to traffic volumes and safety considerations. Authorities will review the operation’s performance and make adjustments as required to facilitate a safe and orderly return journey.
Motorists looking for updates can consult official state traffic websites, radio bulletins and social media channels run by highway operators. Those planning to travel over the New Year period should prepare for possible delays and prioritise safety over speed to ensure a trouble-free start to 2026.
