The A131 Autoroute starts at in the outskirts of Le Havre and ends near Bourneville-Sainte-Croix close to exit 26 on the A13.

It is operated by the Société des Autoroutes de Paris Normandie (SAPN).

Apart from the Pont de Tancarville where a toll is applicable, the motorway is toll-free.

The road section on the Pont de Tancarville is renumbered RN182 to allow non-motorway traffic to cross the Seine.

This autoroute is the result of the merger of the former RN 182, transformed into a motorway between Bourneville-Sainte-Croix and the Pont de Tancarville, and the motorway linking the Pont de Tancarville to Le Havre, originally numbered A15.
