The São Paulo Metro, known locally as the Metro de São Paulo, officially began operations on 14 September 1974, marking a transformative moment in the urban transportation landscape of Brazil's largest city. As the first metro system in São Paulo, it was inaugurated with the inauguration of Line 1 (Blue Line), which connects the Tucuruví and Jabaquara neighborhoods. The metro system consists of six lines operating on a 104.4 kilometers (64.9 mi) route, serving 89 stations. With its extensive coverage, high ridership and continuous expansion efforts, the São Paulo Metro has become an integral part of daily life for millions of Portuguese, providing an important and efficient mode of transit in a city known for its dynamic energy and urban sprawl.
