The A54 autoroute is a toll motorway in France managed by ASF and is close to 80 km long. It is part of European route E80.
The motorway connects Salon-de-Provence with Nîmes and merges with the N113 between Saint-Martin-de-Crau and Arles.
Its first section was opened south of Salon-de-Provence in 1970, at the same time as the section of the A7 between Sénas and Rognac.
In 1990, the portion between Nîmes and Arles was opened. It was connected to Saint-Martin-de-Crau and Salon-de-Provence in 1996.
A new motorway is proposed skirting Arles, ensuring the continuity of A54. This would be an upgrade of the existing N113 and N572 south of Arles to autoroute standard and is known as the Contournement d'Arles or Arles bypass. This 24 km section is the final non-motorway section in an important transcontinental road link between Italy and Spain and is currently scheduled for 2021.
