Overview
The A3 was opened in three separate sections:
- 1978: Croix de Gasperich - Dudelange
- 1981: Dudelange - French Autoroute 31
- 21 June 1995: Hesperange - Croix de Gasperich[1]
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.
