The A31 autoroute, also known as l'Autoroute de Lorraine-Bourgogne, is a French autoroute. The road runs from the Franco-Luxembourg border to Beaune where it joins the A6. The north of the autoroute is free, up to the town of Toul, but it is a toll road south of there. The autoroute serves the cities of Metz, Nancy and Dijon and it is heavily used in the holiday season as it is a convenient route for those travelling from Belgium, the Netherlands, Luxembourg and Germany to get to the south of France.
