Between Abbeville and Rouen, the first part, the motorway was built by the Ministry of Public Works and Transport.^{[clarification needed]} This portion of the motorway, 97 km long, is toll-free.

Between Rouen and Alençon, the second part, the motorway is operated by Alis^{[further explanation needed]} (partly owned by Sanef^{[further explanation needed]}) and is the first autoroute of France to have had offers^{[clarification needed]} by European companies following the withdrawal of the SAPN^{[further explanation needed]} in 1998 despite its contract initiated in 1995.^{[clarification needed]} The second stretch of road, opened on 27 October 2005, is 125 km long and passes over two large viaducts; the Viaduc de la Risle and the Viaduc du Bec.

The third and final stretch of road, between Alençon and the A10 near Tours, is operated by Cofiroute.^{[further explanation needed]} A portion of road between Écommoy and Tours was prevented from being built due to the presence of a protected species of beetle, Osmoderma Eremita, or the Pique Prune.^{[further explanation needed]} Construction began only in 2004, and the stretch was opened on 14 December.
