Sources: 2. Developments: 2. The Santos-Guarujá submerged tunnel project has transitioned from financial and governance structuring to community engagement and social management. Initial developments focused on the establishment of a Technical Governance Committee by the Port Authority of Santos (APS) and the São Paulo state government. This committee was formed to oversee a R$2.6 billion federal contribution toward the total R$7 billion infrastructure plan, ensuring funds are released proportionally to project milestones and compliance with federal requirements. Following these administrative arrangements, the project has moved toward addressing local social impacts. The APS and TSG Concessionária S.A. announced the opening of a community service office in the Macuco neighborhood of Santos to facilitate communication with residents and manage inquiries. This move follows requirements from the Public Ministry for the developer to present removal schedules and provide guidance to families affected by expropriations in the area. ## Timeline ### 2026-08-09: Santos-Guarujá tunnel project to open community service office The Santos Port Authority and TSG Concessionária are opening a community service office in Santos within 30 days to address local inquiries and expropriation concerns regarding the Santos-Guarujá tunnel project 2 sources. https://clstr.news/cluster/santos-guaruj-tunnel-project-to-open-community-service-office ### 2026-07-16: Santos-Guarujá Submerged Tunnel Funding Committee Formed APS and São Paulo signed an agreement creating a permanent committee to manage the R$ 2.6 bn federal funding for the Santos‑Guarujá submerged tunnel, with oversight, escrow controls, and multi‑agency membership 5 sources. https://clstr.news/cluster/santos-guaruj-submerged-tunnel-funding-committee-formed --- Cite as: Santos-Guarujá submerged tunnel project development.
