An innovative recreational space in the capital
The city of Madrid is preparing to take a significant step towards sustainability and urban wellbeing with the development of the Southwest Green Walk, an ambitious project that will transform the surface of the A-5 into an extensive park. This space, which will begin landscaping in September, promises not only to beautify the area but also to offer residents a place to enjoy outdoor activities.
More than 600 workers and 400 machines are currently involved in the excavation works of the tunnel that extends for 3.8 kilometres beneath the motorway. So far, more than two kilometres of this underground work have been completed, allowing the City Council to start planning the future park that will cover this infrastructure.
One of the highlights of the project is the creation of three large hills that will mimic the famous ‘Seven Breasts’ of Vallecas. These hills will be formed with recycled earth from the excavations and will be located where the Alcorcón Substation once stood. This new recreational space will be equivalent to twice the size of Plaza Mayor, providing ample areas for recreation.
The northern hill will be designated for recreational activities and will include seating around a pump track and a skate park. The western hill will serve as a viewpoint, while the southern one will have areas designated for picnic spots. Additionally, some trees removed during the works will be replanted along with another 7,000 new trees that will adorn the entire walk.
The design of the Southwest Green Walk also includes a large segregated bike lane that will connect from Illescas Street to Madrid Río. This path will be signalised and protected by flowerbeds to ensure the safety of both cyclists and pedestrians. The maximum speed allowed will be 20 km/h to ensure smooth circulation.
Solar pergolas, designed to provide shade and self-supply energy to the tunnel, will be installed throughout the park. Four different types are planned: simple, multiple modular, El Greco (taller), and El Batán (with three arches). In total, these pergolas will occupy an area equivalent to three-quarters of a football field.
Apart from the ecological and recreational focus, the project includes significant improvements in urban mobility. The busVAO lanes within the tunnel will allow for more efficient circulation for intercity buses, saving up to 11 minutes per trip during peak hours. This will not only benefit passengers but also contribute to reducing surface traffic on this busy Madrid road.
