This toolbox is the outcome of the Interreg IVB TEN‐TaNS project. The toolbox currently is a beta-version. It contains a selection of transport infrastructure issues where in a majority of the 7 North Sea Region Programme countries, regions have significant responsibilities, according to the project consortium. Please choose a transport mode and cluster. Click “SELECT” to discover where and how your regional authority could contribute to the development of TEN‐T.
