Route nationale 15

The N 15 was a trunk road (Route Nationale) in France.

The RN 15 links the A13 to Le Havre via Rouen and Yvetot.

The RN 15 originates at junction 14 on the A13 autoroute in the Yvelines département near Bonnières-sur-Seine. The road's first few kilometres are notoriously dangerous as the road is a continuous decline towards the river Seine from the A13 autoroute to the RN 13.

After crossing the RN 13, the RN 15 follows the Seine towards Vernon. The RN 15 straightens and leaves the river, passing the town of Gaillon. The road runs parallel to the A13 autoroute and passes through the Forêt de Louviers heading North and over the river at Pont-de-l'Arche onto the right bank of the Seine.

The road follows the river bank overlooked by surrounding cliffs including the Roches de Saint-Adrien. The road meets the Route nationale 14 and enters the capital of Haute-Normandie, Rouen.

The N15 heads Northwest from the city centre and towards Yvetot. It enters the town of Yvetot to continue westwards. The road passes near the town of Bolbec, passes the A29 autoroute, Harfleur and enters Le Havre, ending at the city town hall.
