The N4 road in Belgium is a highway that runs from Brussels to Luxembourg. It starts as chaussée de Wavre at Porte de Namur on the Brussels inner ring and runs south east through Wavre and Namur, Marche-en-Famenne, Bastogne, Martelange and Arlon before terminating as route de Luxembourg at the Luxembourg border. On its route is crosses the Meuse and Lessive Rivers and the Belgian Ardennes. Before the development of motorways the N4 was a main artery for traffic going south east from Brussels and it was dotted with many friteries, cafes and petrol stations.
