The Autoroute 3, abbreviated to A3 or otherwise known as the Dudelange motorway, is a motorway in southern Luxembourg. It is 13.318 km long and connects Luxembourg City to Dudelange. At Dudelange, it reaches the French border, whereupon it meets the A31, which leads to Metz.

Overview

The A3 was opened in three separate sections: The motorway has two lanes in both directions for its entire length, with the exception of a 1.3 km section on the northbound carriageway, where there are three lanes between the Livange/Bettembourg entry slip road (J2) and the Berchem service station entry slip road, where it again merges to become two lanes.
