While researching Madrid’s urban history recently, I discovered that many people are confused about when Madrid Río was officially renamed. As one of Madrid’s most significant urban transformation projects, understanding the evolution of this area’s name is certainly worthwhile.
Actually, the name Madrid Río was officially adopted in 2011. Before that, the banks of the Manzanares River had long been occupied by the M-30 highway, with poor environmental conditions on both sides of the river. Between 2004 and 2011, the Madrid City Council implemented a large-scale urban transformation project, burying the M-30 highway underground and freeing up approximately 10 kilometers of riverbank space. This project cost around 4 billion euros and was one of Europe’s largest urban renewal projects at the time.

Before and After the Renaming
From a timeline perspective, the entire transformation process can be summarized in the following table:
| Period | Status | Characteristics |
| Before 2004 | Occupied by M-30 highway | Severe noise pollution, residents unable to access riverbank |
| 2004-2011 | Renovation construction period | Underground highway project in progress |
| After 2011 | Madrid Río officially opened | 10-kilometer green corridor, 33 bridges connecting both banks |
The transformed Madrid Río includes numerous recreational facilities. There are 17 children’s playgrounds, 3 sports fields, plus dedicated bicycle lanes and walking paths. For residents living nearby, this Madrid Río second-hand housing area has become the preferred location for daily exercise and leisure.
Cultural Significance of the Name
The choice of the name “Madrid Río” is quite meaningful. It’s not merely a geographical description, but represents the Madrid City Council’s vision to reconnect the city with its river. Historically, although Madrid is the capital, the Manzanares River has always had limited water flow, with some people even joking about “selling this river.” However, through this transformation, the river has once again become an important part of urban life.
Madrid Río has now become one of Madrid residents’ favorite public spaces, attracting millions of visitors annually. If you’ve just arrived in Madrid or haven’t visited yet, I highly recommend going for a walk on the weekend. Especially during spring and autumn, strolling or cycling along the riverbank is truly pleasant. It’s also very convenient from the city center—just get off at Legazpi or Marqués de Vadillo metro stations.
