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 the Poitevin Marsh ('' Marais Poitevin'') – disturbing fauna, flora, and the landscapes of this wet marshland. 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 of Saint-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 by Ségolène Royal in 2001, then deputy of Deux-Sèvres. She had had to campaign to ensure the marshland is preserved. Arbitration had been provided by PresidentJunctions
