Southern start of A75 at Pézenas

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 apart from the Millau Viaduct, it is entirely free for the 340 km (210 miles) between Clermont-Ferrand and Pézenas, with extension to Béziers due for completion in spring 2011[1].

South of St. Flour there are excellent views of the Garabit viaduct.

A large portion of the A75 is also part of the European route E11.

Engineering achievements

The building of a motorway across the Massif Central is, in itself, a formidable achievement. Much of the motorway runs at an altitude in excess of 800m (2600ft) with 50km in excess of 1000m (3250ft). [2]

The single most impressive feature is undoubtedly the Millau Viaduct, which carries the road over the Tarn River. It was constructed under a government contract with the Eiffage group, effective for 75 years. Eiffage collects tolls at agreed rates making this the only tolled part of the A75.

Other impressive features include:

Viaducts and bridges

  • Viaduc de la Violette, 560m long, between junctions 21 & 22
  • Pont sur la Truyere, 311m long, between junctions 30 and 31
  • Viaduc du Piou, 414m long, between junctions 38 and 39
  • Viaduc du Ricoulong, 342m long, between junctions 38 and 39
  • Viaduc de la Planchette, 221m long, between junctions 38 and 39
  • Viaduc de la Verrières, 710m long, between junctions 44 and 44.1
  • Viaduc de la Garrigue, 340m long, between junctions 44.1 and 42
  • Viaduc de Millau, 2500m long, between junctions 45 and 46

  • Col d'Engayresque, 888m, between junctions 44 and 44.1

Tunnels

In May 2007, construction started on the final section of the A75, which will see it connected to the A9 autoroute a kilometre or so east of the Béziers east intersection 35. The route will be to the south of the present D609 Pézenas-Béziers road. The section bypassing Valros opened in February 2009. Further sections will be opened in spring 2010. The final section, a gap between Valros and Servian, is scheduled to be completed in spring 2011. According to Serge Cuculière, construction operations manager, the delay is due to difficulties encountered on the section ("Les difficultés recontrées sur la section exigent un temps de réalisation plus important")[3].
