Line 4 (Rio de Janeiro)

Line 4 of the Rio de Janeiro Metro will run from General Osório to Jardim Oceânico. Construction of this line started in June 2010. It will reach the Barra da Tijuca neighbourhood in the West Zone, passing under São Conrado and Rocinha. All stations will be underground, but there will be a bridge leading to a tunnel inside a mountain.

The Government of the State of Rio de Janeiro remains responsible for the expansion of metro network, through Rio Trillhos.
