Immediately to the south of São Bento station, the line emerges from its tunnel in order to use the upper level of the Dom Luís I Bridge to cross over the Douro river.

[1][2][3] The central tunnelled section of line D, including São Bento station, opened on 17 September 2005, with trains initially running between Câmara de Gaia, to the south, and Pólo Universitário to the north.

The platforms are accessed from above via a sub-surface concourse, which is itself accessed from a number of street entrances and by a link corridor from São Bento railway station.

[1][3] Plans were announced in 2017 to build an underground Line G which would connect São Bento with Casa da Música.

The construction started in 2020 and Porto Metro expects it to be completed in July 2025.
