The A8 is an extension of the A7 starting to the west of Aix-en-Provence at La Fare-les-Oliviers. The road passes through the Departments of Bouches-du-Rhône, Var and Alpes-Maritimes. It serves the towns of Aix-en-Provence, Fréjus, Saint-Raphaël, Mandelieu-la-Napoule, Cannes, Antibes, Nice, Monaco and Menton before crossing the border where it becomes the A10 in Italy. It crosses the mountain ranges of Sainte-Baume and of Maures between Aix-en-Provence and Fréjus and the Massif de l'Esterel between Saint-Raphaël and Cannes. Following the Grande Corniche the road offers panoramas of the sea between Nice and Menton.
- 2x3 lanes from Coudoux (the junction with the A7 to La Barque (junction with the A52).
- 2x2 lanes from La Barque to Saint-Maximin-la-Sainte-Baume (being expanded to 2x3 lanes) increases to 2x3 lanes at Cagnes-sur-Mer.
- 2x4 lanes from Cagnes-sur-Mer to Saint-Laurent-du-Var (the road enters the Nice conurbation).
- 2x2 lanes in the section through the southern Alps from Nice Saint-Augustin to the frontier with Italy, this section has 15 tunnels. There is a speed limit of 90 km/h in the tunnels (70 km/h for large vehicles).
The road has heavy traffic all year round and is especially congested in July and August (in particular around Antibes and Nice. As a result, traffic-management schemes have been adopted between Var to Nice-West similar to those on the Péripherique in Paris. The autoroute is regularly closed on the Nice-Menton section as a result of rock falls onto the carriageways. The sections crossing the Maures and L'Esterel mountains are at risk from forest fires in summer.
