Holiday Traffic Snarls São Paulo’s Anchieta–Imigrantes With Over 20 Kilometers of Jams

Overview

• On Friday night, Ecovias reported 19 kilometers of congestion on the Imigrantes (km 34–53) and a stoppage on the Anchieta (km 36–40) toward the coast.
• By Saturday morning, traffic remained slow on the Anchieta (km 26–30) and Imigrantes (km 27–32), with the 7×3 descent operation in effect to increase coastal-bound capacity.
• Ecovias briefly reverted to normal lane configuration on Friday after an unexpectedly strong uphill flow to the capital, signaling that configurations may shift as conditions change.
• Concessionaires forecast more than 40.5 million vehicle movements over the two holiday windows, while RioSP projects over 3 million on Dutra and Rio‑Santos with peak returns expected on January 4–5.
• Routes to the Litoral Norte such as Tamoios, Oswaldo Cruz and Rio‑Santos saw heavy flow, Ubatuba’s Praia Grande was packed with tourists, and a three‑car crash on Dutra in Taubaté caused a 3 km backup with no injuries.
