Overview
- The 1.5 km immersed tunnel will link Santos and Guarujá with about 870 m under the port channel and a six-lane roadway plus a cycle and pedestrian path and space reserved for a future light rail line.
- TSG Concessionária, created by Portugal’s Mota‑Engil, won the 30‑year PPP contract and took operational responsibility as the project entered implementation preparation with detailed design and studies now underway.
- Authorities and company schedules foresee physical work starting in 2027, module fabrication in 2028, immersion and assembly in 2029, and commercial operation targeted for 2031, subject to approvals and land access.
- Financing mixes public and private funds with announced public support of up to R$5.1 billion and a R$2.57 billion state credit structured by Banco do Brasil; the reported government cost estimate of R$6.8 billion differs from a company-cited contract figure near R$7.8 billion.
- Planners say the tunnel could cut current one‑hour ferry or detour trips to about five minutes, serve roughly 28,000 daily users, and create thousands of jobs, but delivery risks include environmental licensing, port operations coordination and potential cost or schedule overruns.
