According to an official source from Metro do Porto, the ceremony will take place on Tuesday afternoon at Caves Ferreira, in Vila Nova de Gaia, in the Porto district, and will mark the last step necessary for the start of the work.

On December 20, the Court of Auditors granted prior approval to the construction contract for the Ruby Line of the Porto Metro, worth 379.5 million euros, a company source told Lusa.

On December 6th, the president of Metro do Porto, Tiago Braga, said that he hoped to be able to commit to the work on the Rubi line between the end of the year and the beginning of 2024, in order to be able to start the works.

The contract for the construction of the Rubi Line of the Porto Metro was signed with the Alberto Couto Alves (ACA), FCC Construcción and Contratas y Ventas consortium on November 3, for more than 379.5 million euros.

The global investment value of the Rubi Line (Casa da Música - Santo Ovídio, including a new bridge over the Douro River) is 435 million, an investment financed by the Recovery and Resilience Plan (PRR).

The Rubi Line, with 6.4 kilometers and eight stations, includes a new crossing over the Douro River, the “Ponte D. Antónia Ferreira, Ferreirinha”, which will be exclusively reserved for the Metro and pedestrian and bicycle circulation.

In Gaia, the stations planned for the Rubi Line are Santo Ovídio, Soares dos Reis, Devesas, Rotunda, Candal and Arrábida, and in Porto Campo Alegre and Casa da Música.

The project must be completed by the end of 2026.
