Route nationale 618

Route nationale 618 or RN 618 was a French national road linking Saint-Jean-de-Luz (on the Atlantic Ocean) to Argelès-sur-Mer (on the Mediterranean). En route it crossed many of the famous passes in the Pyrenees, immortalized by the Tour de France; hence its name was the "Route of the Pyrénées". In 1970, the road was down-graded and is now the RD 918 from Saint-Jean-de-Luz to Arreau and the RD 618 from Arreau to Argelès Plage.
