Western city form has been shaped by a long century of car symbolism that imposed the choice of building infrastructures for a life style based on the exclusive automo- tive option. In the case of Milano, it meant the amputation of its historical devel- opment as an aquatic city by transforming the channel network of Navigli in a grid of roads. Then, the city knew the common fate of sprawling communities plagued by social segregation, long commuting time, pollution due to excessive traffic, loss of identity in dispersed and constantly growing peripheries. Active transport modes have been considered episodically to mitigate the Milano traffic draw- backs but no attempt has been dared to use the transport policy to re-shape the city and make it sustainable, attractive, efficient, and fit for the future challenges. Now, the knowledge that the transport policy deals not solely with the traffic issue but influences aspects as different as integration, access to job market, recrea- tion and educational opportunities, safety, local economy and cohesion, health costs has been exploited by several other municipalities to revolutionize the structure of their cities starting from the reconversion of the infrastructures. Active modes, and cycling in particular, became the lever to invert the car-based devel- opment trend and to transform the lame metropolis populated by isolated individ- uals into a dynamic entity with brilliant community life. Milano could profit as well from a similar vision of alternative transport policy. A network of effective bicycle routes would not only alleviate vehicular traffic and pollution, but would offer physical connectivity to the dispersed
