The A75 is an autoroute (motorway) in France.

Known also as la Méridienne, it is a developmental project with the aim of speeding up and reducing the cost of car travel from Paris southwards, and it is entirely free for the 340 km (210 miles) between Clermont-Ferrand and Béziers.

It passes over the Tarn River on the Millau Viaduct, which was constructed under a government contract with the Eiffage group , effective for 75 years. Eiffage will impose tolls at agreed upon rates: about €4.90 for light automobiles, excluding the peak months of July and August (€6.60).
