What was presented
On June 9, 2025, the government agencies involved presented a plan for a connection between Estácio and Praça XV, Line 3 from Praça XV to Guaxindiba via Niterói, and an extension of Line 4 to Recreio.
The official communication estimated R$28.8 billion, 31 new stations and 44 additional kilometers, with the first sections expected in 2031 and total completion in 2032.
What's missing between presentation and boarding
Metro projects require demand and engineering studies, route definition, environmental analysis, expropriations, financing model, bidding, contracts and works. Some of these steps may occur simultaneously, but none should be assumed.
- Feasibility study completed and published.
- Formalized source of resources for each section.
- Licensing and authorizations.
- Basic and executive project.
- Notice, winner and contract.
- Work started, physical progress and testing.
- Authorization and start of commercial operations.
How to follow without falling for eternal advertising
BuzuRadar must maintain a dated, documented status record for each section. Deadline changes should be recorded without erasing previous forecasts.
It is also important to evaluate integration with buses and BRT, access to stations and distributional effects. A new line can reduce average times and still leave vulnerable areas without benefit if the feeder network does not keep up.
