Design and construction of the extension of the new section of line 2 of the Madrid Metro, with a total length of 4,107 meters and in which 4 stations were built: La Almudena, Alsacia, Avenida de Guadalajara and Las Rosas.
The tunnel is being executed using various methods:
- 3,817 using an EPB TBM with a 9.20 meters excavation diameter, lined with 32 centimeters thick, reinforced concrete voussoirs.
- Tunnel between cut-off walls of 0.80 and 1.00 meter thickness, with a 20 meters mean depth and 249 meters long.
- Tunnel executed using the traditional Madrid method, 28.60 meters long.
The route begins in the Bilbao district, where the first station is located, to facilitate access to La Almudena Cemetery. From there the tunnel continues along under Calle Nicolás Salmerón to the second station, then runs along Avenida de Guadalajara to the third station at the junction with Avenida de Canillejas to Vicálvaro and finally crosses the M-40 bypass dual carriageway and continues until it reaches Paseo de Ginebra, where the fourth station is located.
All stations have 90 meters long platforms and are accessible to handicapped persons, so that everybody, without any exceptions, is able to enjoy this public transport network.
Specifically, 13 lifts and 28 mechanical stairways have been installed in the new stations, equipped with tactile paving for the guidance of visually-impaired people, hand rails for disabled people, Braille signage and other complementary measures that increase station accessibility.
- Improvement of communications by providing service to more than 65,000 people.
- A tunnel executed using three different methods.
