The Expansion of Metro Line 11: Connecting Madrid Efficiently
The Community of Madrid has officially approved the informative study for the northern section of Metro Line 11, marking a significant milestone in the expansion of the metro network. This ambitious project aims to create a new route stretching from Mar de Cristal to Valdebebas Norte, featuring six strategically located stations. Key stops will include the Ifema fairgrounds, the Isabel Zendal Nursing Hospital, and Terminal 4 at the Adolfo Suárez Madrid-Barajas Airport.
Why is This Expansion Important?
Metro Line 11 is the least utilized line within the entire Madrid Metro system. The administration has recognized its potential and is now investing in its expansion to better serve areas with high demand for public transportation. The goal is to transform this line into a major artery that crosses Madrid from southwest to northeast, thereby improving access to essential locales and infrastructures like the airport.
Understanding the Project Figures
Recent reports from Europa Press indicate that the initial budget for the base tender for this project is approximately 599.3 million euros, excluding VAT. With a favorable environmental impact report already in place, construction is set to commence in 2027 and is expected to span roughly three years and three months. The new section will encompass an 8.2-kilometer tunnel and connecting branches to Line 8 at Mar de Cristal, enhanced by future connections to the Barajas depots.
Stations Along the New Route
The approved route will feature six key stations:
- Mar de Cristal – Convenient connections to Lines 4 and 8 beneath Arequipa Street.
- Ifema-Cárcavas – Adjacent to the fairgrounds with proximity to a future Formula 1 circuit.
- Valdebebas/Ciudad de la Justicia Interchange – An intermodal hub linking Cercanías, buses, and Metro.
- Isabel Zendal Nursing Hospital – Located just 150 meters from the health facility.
- Terminal 4 – Close to the airport and future high-speed station with a connection to Line 8.
- Valdebebas Norte – Near the upcoming Valdebebas Shopping Center.
Future Expansion Possibilities
The design allows for the potential addition of two more stations: one in the Cristalia area and another in Valdebebas. This flexibility is intentional, enabling the metro to adapt as these neighborhoods continue to grow and develop urban infrastructures.
How Will the Excavation Be Conducted?
Most of the tunnel construction will utilize a tunnel boring machine, dividing operations into two segments. One section will dig from an attack well on Fernando Higueras Street to Mar de Cristal, while another will start from Secundino Zuazo Avenue. In some urban areas, manual methods like pick and shovel will be employed to minimize disruption and noise pollution.
Current Status of Other Sections
As work on the northern section gets underway, the central section between Plaza Elíptica and Conde de Casal has already surpassed 50% execution with five stations planned and an investment close to 500 million euros. Conversely, the section between Conde de Casal and Hortaleza, which will feature 14 stations, remains stalled pending resolution of its subsections.
Addressing Neighborhood Inequality
While this project aims to enhance transportation in Madrid, debates over station distribution have emerged. Valdebebas, with a population of around 30,000, will receive multiple stops, while areas like Las Águilas, home to 50,000, have been excluded from the southern route. This disparity has sparked protests regarding equitable access to public transport.
What Happens Next?
With the final approval of the informative study granted, the next phase will involve bidding for construction in the coming months. If timelines align, work should kick off in 2027, potentially leading to operational connections by 2030.
