Line 4 (Rio de Janeiro)

Line 4 (Yellow) of the Rio de Janeiro Metro is the third metro line built in the city of Rio de Janeiro. It was completed on 30 July 2016, connecting the Barra da Tijuca neighbourhood in the West Zone, passing under São Conrado and Rocinha, to Ipanema in the South Zone. All stations are underground, but when arriving in Barra da Tijuca, trains exit a tunnel, pass briefly by an elevated bridge and go underground again.

At first, the line was only open to those with a ticket to events of the 2016 Summer Olympics and members of the Olympic Family. It later opened to the general public, in September 2016.

There were six exclusive stations planned for Line 4: Jardim Oceânico, São Conrado, Gávea Station, Antero de Quental, Jardim de Alah and Nossa Senhora da Paz. However, as of April 2023, Gávea Station remains incomplete, and is the only planned station for Line 4 that hasn't yet become operational.
