The Line 22 Marrom project, a new subway line that will connect São Paulo to Cotia, is underway. Understand the current stage of this important development in urban mobility in the metropolitan region of São Paulo.
The next big step in expanding São Paulo's metro network is the implementation of Line 22 Marrom. This project aims to connect the capital of São Paulo to the municipality of Cotia, covering a 29 km route with 19 planned stations.
In May 2023, São Paulo Metro hired the Sista Prime consortium to prepare the preliminary engineering project, architecture and geology of Line 22. The consortium, formed by the companies Sista (or Sistra) and Prime, has a period of 35 months to complete this work, extending until May 2026.
Next stages
After completion of the preliminary engineering project, São Paulo Metro will contract the basic design of the line. This phase is expected to begin in mid-2026 and, considering an average of two years to complete, it is estimated that the essential studies for Line 22 will be completed between 2028 and 2029. This indicates that the The start of actual works on the project may only occur at the end of the decade or in the early 2030s.

Line 22 is crucial to improving urban mobility between São Paulo and Cotia, an area with an intense flow of passengers. By providing a fast and efficient transport alternative, the line will alleviate traffic on the roads and contribute to reducing pollution.
Official perspective
The São Paulo Metro, to date, has not established an official deadline for the completion of Line 22. Currently, the institution is focused on preparing the preliminary engineering and geology, a crucial step for the advancement of the project.
Despite the long period expected until the complete operation of Line 22, it is important to recognize the advances in the expansion of São Paulo's metro network. This line represents an important milestone in the development of urban mobility in the region, promising significant improvements in public transport and citizens' quality of life.
