The A115 autoroute is a motorway in Île-de-France in France. It is a 10.7km (06.6miles) long spur of the A15 autoroute, linking it to the RN 184 near Méry-sur-Oise.
The motorway first linked Sannois to Beauchamp then Taverny in 2000 by a 1 km long tunnel. The last part of the motorway was opened in September 2004, linking Taverny to Méry-sur-Oise and thus linking the RN 184 to the A15.
