 The motorway was to be extended south, connecting Pau to Oloron-Sainte-Marie as the A650 but the project was abandoned in 2008.It would have started at the interchange with the A64 Bayonne - Toulouse autoroute at Poey-de-Lescar and would have run as far as the bypass of Oloron-Sainte-Marie.The ultimate aim would be to connect to the Somport Tunnel to Spain.
