The development of segregated road infrastructures in the Metropolitan Area of Barcelona has generated high demand of traffic and the negative externalities associated with this. It has also conditioned the urban metropolitan structure and generated significant infrastructural barriers. It is as necessary to promote physical channels of priority for sustainable transport as it is to connect the city on a more human scale. This article presents some of the initiatives of the Metropolitan Area of Barcelona (AMB) for achieving this, particularly a network of metropolitan avenues as a structure for boosting sustainable transport and connecting the metropolitan city. The conceptualization of this network is explained, along with its implications at both a local level and a metropolitan/regional level with its coordination with segregated roads.
