This book and exhibition's title represent the millenary importance of communication in the Mediterranean arc, since the Roman road Via Augusta followed the peninsular coastline from Cádiz to the Pirineos and served as the grounding base for the railway network of nowadays that is planned to be completed. Saying it's unfinished comes from a lack of coordination in the policies of middle and modern ages. When it arrived in the 18th century, it had a radial disposition from Madrid and in the 21st century, we still discuss its possibilities within the Transeuropean Transportation Network. Much archive documentation was needed for this project in order to understand the social, cultural and economic context to sparked the specific demands for infrastructure improvementin a vibrant moment of agriculture exportation, growing industry and tourism. The social, economic and political reality prevented and pushed back most of the proposals. For our current time, the demands were important, but also discovering the cause of failure in advancing and adapting to new realities and needs in a constantly-changing world. The Corredor Mediterráneo (Mediterranean Runner) defended by people like Ignacio Villalonga over a hundred years ago runs now within the top european priority runners network as a chance for a future, solid, united and connected Europe.
