Route nationale 1

The Route nationale 1 is a trunk road (nationale) in France between Paris and Calais. It is approximately 339 km (211 mi) long.

The majority of the original road has been superseded by the A16 autoroute. As a result much of the road has now been reclassified the RD 1001, RD 901 and RD 940.

Paris - Saint-Denis - Beauvais - Amiens - Abbeville - Boulogne-sur-Mer - Calais - Dunkerque - Belgium

The road begins at the Porte de la Chapelle in Paris and runs below the A1 autoroute as the Boulevard de President Wilson north through the northern Paris suburbs to Saint-Denis. The road heads through Saint Denis as the Avenue Lenine before heading north east. The road then heads to the east of Saint Brice Sous Foret, with the Foret Dominiale de Montmorency.

The road heads into the Foret Dominiale de L'Isle-Adam where the A16 autoroute starts, and then crosses the River Oise. The autoroute heads to the west while the N 1 heads out over rolling countryside northwards after Chambly. The road heads through Noailles before the road crosses the autoroute and enters Beauvais.

The road passes round the east of Beauvais passing the airport before turning north east. The road heads over the generally flat countryside to Breteuil. It runs parallel to the A 16 and enters the town of Amiens from the South. The road crosses the River Somme in the town.

In Amiens the road turns north west along the Somme valley past the memorial Samara. The road heads out of the steep valley sides before the town of Abbeville. To the west of the town is the A28 autoroute which heads south to Rouen.
