A major cross-road city in Europe, Basel presents a surprising way of organizing its transport hubs. To further its development, the city has been forced to reconcile several geographical constraints : the territorial exiguity along the narrow Rhine valley, and the double border line with France and Germany. Given that its transport function constitutes a permanent risk for disruption, Basel has made it a priority to invest in the urban planning of its transport networks. Basel has thus been engaged in an tireless construction work of the city and its transport networks, whose effectiveness is an indisputable gauge for success. Such articulation condenses in singular devices, which one can consequently describe as 'border nodes'. They present themselves as hybrid devices, both technical and legal, nodes of circulation, where the management of international traffic flows is inseparable from their insertion in the central urban space.
