Transversal highway: The Catalonia Trans-European Corridor

Widening of the Transversal Axis was made possible thanks to the public-private agreement model: Cedinsa put its capacity to attract investment and its technical and managerial excellence at the Government’s service to successfully undertake a project of great public interest. In 2010 Cedinsa was awarded the  European Shadow Toll Deals of the year granted by Euromoney for the financing of Eix Transversal.
