The tender now continues with a “period of prior hearing, in which the candidates can present questions and possible complaints” and, after that, Metro do Porto will invite the pre-qualified companies “to present their price proposal for the execution of the two network expansion contracts”.

“This involves an overall investment in the order of €300 million, which will add six kilometres to the Metro network”, the company told reporters.

The projects involve the extension of the Yellow Line, between Santo Ovídio and Vila d’Este, in Vila Nova de Gaia, and the construction of the Circular Line (Pink Line), between Alliados/Praça da Liberdade and the Casa da Música, in Porto.
