Movements, fluids, itineraries, journeys, links... Words for an urban discourse characterised by the particular aspect we have as citizens living in an "endless roaming". Every day, we collectively use a range of itineraries, directions, addresses, courses, journeys, paths, walks, sailings... on a backdrop that is technological, fluid, liquid, etc. and built in terms of a miscellanea of spaces that allow us to come and go from one urban node to another.


This article is divided in terms of two clearly differentiated moments. In the first, more theoretical, part, we emphasise, on the one hand, the architectures in these spaces that allow for mobility in today's city and the types of urbanisation that lead to them; and, on the other, we highlight the types of social practices seen in these types of spaces. In the second, more descriptive, part, we present and analyse the strategy seen in Barcelona, through the construction of new infrastructures for mobility, of which some examples are given, to connect to other mobile cities and, thus, to avoid becoming an unused world urban node.
