A75 near Massiac

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).[2]

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

• Viaduc de la Violette, 560 m long, between junctions 21 & 22
• Pont sur la Truyère, 311 m long, between junctions 30 and 31
• Viaduc du Piou, 414 m long, between junctions 38 and 39
• Viaduc du Ricoulong, 342 m long, between junctions 38 and 39

• Viaduc de Verrières, 710 m long, between junctions 44 and 44.1

† The section between junctions 59 and 61 (the Pézenas by-pass) was not technically motorway and was still designated as the N9, despite the depiction on most maps. Work to upgrade the section to full motorway status was carried out between September 2013 and June 2014.

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").[1]
