The Green and Yellow line extension is the most significant upgrade to Lisbon’s rail underground network in the last decade. By creating a new connection between the two existing lines, this project will enable forming a circle line which will enhance the usability of public transportation services in the city centre.
The project comprises a total of 1984 meters of running tunnels, two new underground stations, upgrades at Rato and Cais do Sodré stations and a new flyover at Campo Grande. Running tunnels and station platform tunnels will be excavated using the NATM/SCL construction methodology. The project includes many technical challenges, such as running tunnels gradients of up to 4%, and variable geological and hydrogeological conditions.
Tunnelling has already begun in April this year for Construction Package 1 and enabling works for Construction package 2 started in June. Services are planned to start in Q4 2024.
In this presentation, Francisco will provide an overview of the extension works, the associated challenges and proposed solutions.
