Review of the design study for the extension of the metro in Lisbon
This involves building:
- a new 1,984 m long double-track tunnel between Rato and Cais do Sodré comprising two new stations (Estrela and Santos),
- two new viaducts at Campo Grande.
These works will enable a circular line integrating the green line and the yellow line, which were previously independent
