# Infrastructure and maintenance works in Brazil > Live situation record from CLSTR: https://clstr.news/situations/infrastructure-and-maintenance-works-in-brazil > Updated: 2026-10-22T23:52:23.000Z. Sources: 44. Developments: 4. Infrastructure developments and maintenance activities continue across several Brazilian cities. In Rio de Janeiro, scheduled nighttime closures were announced for the Rebouças Tunnel, the Vice-President José Alencar Tunnel, and the Presidente Itamar Franco Elevated Highway to facilitate maintenance. Subsequent reports highlighted additional closures for the Santa Bárbara, Zuzu Angel, and Acústico Rafael Mascarenhas tunnels, as well as the Engenheiro Freyssinet and Rufino Pizarro elevated structures. Newer updates specify planned traffic interdictions for the night of October 22-23, 2026. These include the closure of the lower deck of the Elevado das Bandeiras toward São Conrado, the Vice-Presidente da República José Alencar Tunnel toward Barra da Tijuca, and the Rebouças Tunnel toward Lagoa. CET-Rio operators are tasked with monitoring traffic and adjusting signal timings to manage diversions. Specifically, the Elevado das Bandeiras closure will divert traffic to the upper deck, while the José Alencar Tunnel closure will redirect vehicles via Serra da Grota Funda (Avenida Artur Xexéo), with BRT buses following specific detour protocols. During the Rebouças Tunnel closure, the opposite direction will utilize a reversible lane toward Zona Sul. In São Paulo, the Via Dutra highway underwent asphalt recovery and microfresing, while the São Paulo Metro began excavations for the Line 2-Green extension to Guarulhos. In Curitiba, urban interventions including drainage works were initiated. Safety concerns persist in Mato Grosso, where a public hearing addressed difficulties for residents crossing the duplicated BR-163 highway in Nobres. Additionally, the government of Mato Grosso do Sul announced R$ 100 million in emergency investments to improve traffic and safety on highways within the Vale do Ivinhema region. Administrative updates involve the Amazonas state and Manaus city governments adjusting public servant holidays for late October to manage expenses. ## Timeline ### 2026-10-22: Rio de Janeiro scheduled road closures for maintenance Rio de Janeiro has announced maintenance-related closures for Elevado das Bandeiras, Túnel José Alencar, and Túnel Rebouças scheduled for the night of October 22 and early morning of October 23. 6 sources. https://clstr.news/cluster/rio-de-janeiro-scheduled-road-closures-for-maintenance ### 2026-10-20: Brazil infrastructure and public service updates Regional reports from Brazil cover R$ 100 million in road emergency funds in Mato Grosso do Sul, election-related logistics in Amazonas and Mato Grosso, and STF rulings on traffic enforcement in Rondônia. 35 sources. https://clstr.news/cluster/rio-de-janeiro-tunnels-and-elevated-highway-scheduled-for-maintenance ### 2026-10-17: Rio de Janeiro infrastructure faces safety concerns and maintenance closures Rio de Janeiro faces infrastructure challenges, including safety concerns at Passeio Público due to missing manhole covers and scheduled maintenance closures for several tunnels and elevated roads. 4 sources. https://clstr.news/cluster/rio-de-janeiro-infrastructure-faces-safety-concerns-and-maintenance-closures ### 2026-10-13: Rio de Janeiro and São Paulo announce major infrastructure and road works Major road maintenance, tunnel closures, and subway expansions are underway in Rio de Janeiro, São Paulo, and Curitiba. 10 sources. https://clstr.news/cluster/rio-de-janeiro-road-closures-announced-for-october-13-maintenance --- Cite as: Infrastructure and maintenance works in Brazil.
