The works consist of dams, sluices, locks, levees, and storm surge barriers. The works were initiated after the North
Motorways of the Sea land. The routes selected to be Motorways of the Sea should be able to maintain a series of quality criteria; these pertain to frequency, port to port costs, simplicity of administrative tasks. Future routes should compensate for congestion experienced, for example when crossing the Channel (as the similar road networks should do for routes crossing the Alps or the Pyrenees). One envisaged impact of the Motorways of the Sea is energy savings, pollution reductions and more capacity on current overland European transport networks. The adoption of Article 12a of the TEN-T by Council and European Parliament gave a legal framework
