The Autoroute 1, abbreviated to A1 or otherwise known as the Trier motorway, is a motorway in Luxembourg. It is 36.203 km 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.

In all, the A1 was opened in six separate sections:
