Course of the road

The N100 A was a French national road established in 1875 as a link between the N100 and the N94. It ran in the valley of the Durance and had a length of 3 kilometers. In 1933 this was renumbered to the N100 C. At the same time, a new N100 A was established between Digne-les-Bains and south of Seyne in the Bès valley, where it ran as an alternative route to the N100. In 1961 it swapped its course with the N100. This took place in connection with the damming of the Lac de Serre-Ponçon, which in addition to sections of the N94 and N100 also flooded the old route of the N100 A from 1875. In 1973, the ratings were the newer route to the D900 A . In 1974 the number was used for Remoulins' new east bypass, which led from the N100 to the N86. This became the N101 in 1978.
