The European route E 15 is part of the United Nations international E-road network. It is a north-south “reference road”, running from Inverness, Scotland south through England and France to Algeciras, Spain.[1] Along most of its route between Paris and London, the road parallels the LGV Nord (as the French A1 autoroute) and High Speed 1 (as the English M20 motorway).
