The Autoroute 1, abbreviated to A1 or otherwise known as the Trier motorway (French: Autoroute de Trèves), is a motorway in Luxembourg. It is 36.203 kilometres (22.496 mi) long and connects Luxembourg City, in the south, to Wasserbillig, in the east. A few hundred metres to the north of Wasserbillig, it reaches the German border, whereupon it becomes the A64, which leads to Trier.
