The A16 autoroute – also known as L'Européenne and forming between Abbeville and Dunkirk a part of the larger Autoroute des estuaires – is a motorway in northern France.
The motorway, which has a total length of 319 km, starts at L'Isle-Adam in Île-de-France and ends at the Belgian frontier near Bray-Dunes, serving en route Beauvais, Amiens and Abbeville in Picardie, Boulogne-sur-Mer, Calais and Dunkirk in Nord-Pas-de-Calais. From Abbeville, the A16 runs parallel to the English Channel and then the North Sea coast.
The motorway was built in the 1990s to relieve the congested RN1 between Paris and the Côte d'Opale (Boulogne and Calais). Between L'Isle-Adam and Boulogne it is operated by the Société des Autoroutes du Nord et de l'Est de la France (SANEF) and is tolled. From Boulogne to the Belgian border it is managed by the Direction Départementale de l'Équipement (DDE), which does not impose a toll.
