A75 autoroute
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 between Clermont-Ferrand and Béziers. It was due for completion in spring 2011, but was fully open in December 2010. 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 800 m (2600 ft) with 50 km in excess of 1000 m (3250 ft). The single most impressive feature is undoubtedly the Millau Viaduct, which carries the road over the Tarn. 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 Passes Tunnels The route. In May 2007, construction started on  the final section of the A75, a connection from Pézenas to the A9 autoroute a kilometre or so east of the previous Béziers east intersection 35. The route to the south of the present D609 Pézenas-Béziers road bypassing Valros opened in February 2009. Further sections opened in spring 2010. The final section, a gap between Valros and Servian, was completed in December 2010. According to Serge Cuculière, construction operations manager, the delay was due to difficulties encountered on the section (""Les difficultés recontrées sur la section exigent un temps de réalisation plus important"").
