They've been talking about this every since I've been here, so for at least five years now, with estimates of it opening in 2015. Part of the point of the airport is to divert some of the traffic away from the airports in Paris. It will be located Northwest of Nantes, along the N165. I drive that road quite regularily, and there are always all kinds of signs of protest - residents worried about increased traffic, noise, etc. I for one am looking forward to it because of the direct flights to the US that it will likely offer - it's such a pain to have to take the train to Paris all the time with all that luggage, and it would be mille fois easier if I could just park & fly from Nantes.
