A road network with a regional, national and international vocation
Normandy benefits from links with neighbouring regions and with major European routes
Calais-Bayonne motorway, "Estuaires" (Estuaries) motorway: A13, A28, A84 and soon the A88, and only a short distance from the A10 and the A11

The Estuaries motorway is a road network covering 1,300km linking Dunkirk to Bayonne and bypassing Paris. The motorway owes its name to the four major estuaries it crosses: the Somme, the Seine, the Loire and the Garonne. This Estuaries motorway is a crucial link in the French portion of the European north-south motorway, facilitating exchange between Spain - the French Atlantic and Channel coastlines - Great Britain and Northern Europe.
The Pont de Normandie (Normandy bridge), connecting the Upper and Lower Normandy regions, crosses the Seine and links Le Havre (Seine Maritime) on the northern bank, to Honfleur (Calvados) on the southern bank.
On its southern portion, the Estuaries motorway follows, first of all, the A13 from Honfleur to Caen for 95km (3 tolls) then the A84 from Caen to Rennes (toll-free). The A84 crosses Calvados then Manche over a distance of 115km (Saint-James). The motorway links Caen to the south Manche (Avranches) in less than an hour, and Caen to the centre of Rennes in one hour and a quarter.
This motorway is a major North-South exchange and heavy transport route, from Picardy, Normandy, Brittany and Pays de la Loire to Aquitaine, in other words, France's entire English Channel - Atlantic shoreline.
The motorway successively follows the A16 to Abbeville then the A29 to Le Havre, the A13 to Caen, the A84 to Rennes, the RN137 (dual carriageway) to Nantes, the A83 to Niort, the A10 to Bordeaux and, finally, the A63 to Bayonne. The A11 motorway links Paris and Nantes via Le Mans and Angers. It is also referred to as the "Océane". The motorway was completed on the 24th of April 2008 with the opening of the Angers bypass. At Le Mans, the interchange between the A28 and the l'A11. At Tours, the interchange between the A28 (Le Mans – Alençon – Rouen) and the A10, also referred to as the "Aquitaine" and linking Paris to Bordeaux via Orléans, Tours, Poitiers and Niort (the portion between Saintes and Bordeaux is part of the Estuaries motorway).
The Calais-Bayonne route is part of the master development and planning scheme for roads and motorways dated March 1987. It represents 1,050km of exclusive motorway, with the exception of the stretch passing through Rouen. In its northern portion, the route follows the A16 to Abbeville, then the A28 to Tours. The A28 motorway (Rouen – Alençon) portion was inaugurated in October 2005. The A28 from Rouen to Alençon in a few figures:125km, 2 major viaducts, 5 arterial interchanges, 1 interchange (A13), 1 motorway node (A88) in the vicinity of Sées, 6 service and rest areas, 1 motorway toll gate. New business parks have been developed to welcome businesses alongside the A28 in the vicinity of Gacé, Sées and Alençon. The A28 relieves the RN138 (A road) of part of its heavy goods traffic, thus rendering travel across the department safer and less time-consuming. Via the motorway, Rouen is approximately an hour's drive from Alençon, Argentan or L'Aigle, compared to a 2 hour drive by road. By the autumn of 2010, the motorway network will be complete with the opening of the final portion of the A88 linking Caen, Falaise and Sées. The region has mobilised the required funds to build the A88, a strategic and essential link between Caen and the A28. The project is a key asset in Normandy's strategic position since it facilitates transport to the region's ports and offers improved regional cohesion by linking the conurbations of Caen and Alençon.
The 225km long A13, also known as the "autoroute de Normandie" (Normandy motorway), links Paris to Caen via Rouen. France's first ever motorway, the A13 from Rocquancourt and Saint-Cloud, was built in 1941, during World War II. A portion originally planned to be opened in 1941, was in fact only inaugurated in 1946 (Rocquencourt-Orgeval portion). The opening of the A13 resulted in the construction of the Saint-Cloud bridge in 1974; prior to which the motorway came to an end at this point. The motorway is since linked to the Paris bypass via the Saint-Cloud viaduct and the Boulogne tunnel.
