Paris to Évreux, km 0 to km 91 ,
Yvelines The road begins at
Porte Maillot, one of former gates in western
Paris, in direct alignment with the
Champs-Élysées. Continuing on this alignment, the road reaches
La Défense after crossing the
Seine. Then, as the Boulevard circulaire, orbits around La Défense. To the west of La Défense, the
A14 autoroute leaves Paris towards
Orgeval and the
A13 autoroute. Breaking from its previous straight course, the N13 follows the curves of the river Seine to reach
Saint-Germain-en-Laye, passing
Nanterre,
Le Port-Marly on the way. Exiting
Saint-Germain-en-Laye and
Chambourcy, the N13 resumes a linear course towards
Normandy, crossing the
A13 autoroute at
Orgeval. The road heads West through
Aubergenville and
Mantes-la-Jolie. At
Bonnières-sur-Seine the
N 15 to
Le Havre branches off North-West while the N 13 heads West. The road crosses the A13 again through rolling countryside to
Pacy-sur-Eure and then to
Évreux. There, a junction here with the
RN154 was built in the 1990s following the upgrading of the N154 to motorway status from
Louviers to
La Madeleine-de-Nonancourt.
Évreux to Caen, km 91 to km 210 The road between
Évreux and
Caen follows a straight course of a former Roman road linking Paris to Normandy. The road crosses the river
Risle and the
A28 autoroute at
La Rivière-Thibouville. The road bypasses the town of
Lisieux before dropping into the Plaine de Caen, where it crosses the river
Dives. The road then heads Northwest into
Caen in which the N13 is now de-classified.
Caen to Cherbourg km 210 to km 331 After
Caen, the road continues northwest past the
Ardenne Abbey and around the historic town of
Bayeux. The road's old course out of Bayeux has been numbered RD 513 while the new road, a
dual carriageway, follows a non-linear course towards
Carentan. The road passes the small town of
Carentan and turns North towards
Valognes and then the port of
Cherbourg. Carentan bypass, built between 1994 and 1996, goes underneath the Canal de Carentan, where signals control access to the tunnel below the waterway. ==Village étape==
