Route nationale 13

The N13 is a trunk road (nationale) in France between Paris and Cherbourg.

The road begins at Porte Maillot, one of former gates in West Paris', in direct alignment with the Champs-Élysées. Continuing on this alignment, the road reaches La Défense after crossing the River 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.
