TheA83 autoroute is a motorway inFrance. It is in the departments of Pays-de-la-Loire and Poitou-Charentes operated by ASF. It connectsNantes toNiort viaFontenay-le-Comte. The motorway has a junction with theA10 at Niort which gives access to the north and toBordeaux connection. The A83 forms part of theAutoroute des Estuaires. The total length is 152.5 km. It is also part of theEuropean route E3.
The A83 was only finally opened in 2001 with the opening of the section between Oulmes and Niort. This last part of the route put an end to a long debate since 1987. The A83 was originally to join the A10 by circumventing Niort to the south passing close to Coulon and Magné. This route was more direct but crossed thePoitevin Marsh (Marais Poitevin) – disturbing fauna, flora, and the landscapes of this wetmarshland.
A83 was opened between Nantes and Oulmes while a more environmentally friendly route was sought. The southern layout close to Niort had two problems wet marsh and the urbanized district ofSaint-Liguaire. Finally, in 1992, a longer route to the north of Niort was selected. This was supported by the Local authority as it served more of its district. The last 34.4 km between Oulmes and Niort were opened bySégolène Royal in 2001, then deputy of Deux-Sèvres. She had had to campaign to ensure the marshland is preserved. Arbitration had been provided byPresidentFrançois Mitterrand.

The A831, will connectRochefort (A837) with Fontenay-le-Comte (A83). The route between Nantes and Bordeaux will be via A83 between Nantes and Fontenay-le-Comte, the A831 between Fontenay-le-Comte and Rochefort, the A837 between Rochefort and Saintes and the A10 between Saintes and Bordeaux. In spite of the many different motorways involved the route will be shorter.
A831 is currently only a proposal declared by a Public Utility Decree by the State Council on July 12, 2005. The next stage is the awarding of the concession to run the motorway. The road will however have to cross thePoitevin Marsh and Rochefort Marshes, the two great wetlands of the Atlantic Coast, which probably be challenged.
