It is quiet, it does not pollute and those who use it for transportation claim to be happier since they got on it. It is the bike, that means of transport that was born in early S. XIX and a fashion that seems to return with those that are more aware of change climate. In Madrid, where pollution levels have risen alarms these days in Europe, there is increasing interest in the promotion of cycling.
Madrid’s green belt was created a few years ago, around 2007: A way for cycling around the city that gave ACCIONA the chance of being part of the construction of some bridges, as you can see in this video. Have you ever done this route? What do you think about it?
