The A63 autoroute is a motorway in southwest France, connecting Bordeaux (from Junction 15 of the Rocade) to the border with Spain. The RN10 does not exist anymore and became a full toll road which crosses Les Landes (moorland) as a dual-carriageway.
The road is an important axis of communication between the French and Spanish Basque Country.
It is part of the Autoroute des Estuaires and is used by lorries from all over Europe heading to the Iberian peninsula. In addition, the road is connected at Bayonne with the A64 to Pau, Tarbes and Toulouse.
The northern section has junctions with the A660.
- The A63 was operated by the Autoroute Company de la Cote Basque (ACOBA) in 1984.
