The Government of the State of São Paulo, through the Secretariat for Partnerships and Investments (SPI), has launched a public consultation for the Public-Private Partnership (PPP) project of Metro Line 16-Violet, which aims to connect the eastern and western zones of the city.

With an estimated investment of R$37.5 billion (US$7 billion), the first phase of construction for the new line will cover 19 km and include 16 stations (Teodoro Sampaio, Oscar Freire, Nove de Julho, Jardim Paulista, Parque Ibirapuera, Dante Pazzanese, Ana Rosa, Parque Aclimação, Parque Independência, São Carlos, Paes de Barros, Vila Bertioga, Álvaro Ramos, Regente Feijó, Anália Franco, and Abel Ferreira). In this section, the line is expected to transport an average of 475,000 passengers per day by 2040. 

Line 16 is expected to include eight interconnections:

• Line 1-Blue at Ana Rosa station;
• Line 2-Green at Ana Rosa and Anália Franco stations;
• Line 4-Yellow at Oscar Freire station;
• Line 6-Orange at São Carlos station;
• Line 10-Turquoise at São Carlos station;
• and future lines: Line 19-Celeste at Jardim Paulista station; Line 20-Pink at Teodoro Sampaio station; and Line 22-Brown also at Teodoro Sampaio station.

During the public consultation period, from October 6 to November 7, 2025, the public may submit suggestions to improve the project. Contributions must be submitted in writing, exclusively via email to ppplinha16@sp.gov.br, using the standard form available on the project page on the SPI website (under the “Public Hearings and Consultation” section).
