From this Saturday evening, the Micheville tunnel in Belval will be closed to traffic for more than two months. Diversions will be put in place, which are expected to aggravate the already congested traffic.

Works are scheduled to start on Saturday 18 March at 8pm and are planned to be completed on 29 May at around 11pm. During this time, traffic in the Micheville tunnel will be disrupted in the direction of Audun-le-Tiche in France, as well as towards Luxembourg.

Traffic towards the Grand Duchy will be diverted via Route de Belval (CR168) and Boulevard du Jazz (CR191). In the direction of France, traffic will be diverted via Boulevard des Lumières (CR191B) and Route de Belval.


The temporary roundabout at the entrance to Belval will be removed. It will be replaced by a tunnel connection to the new section leading directly to the A4, the Esch motorway that leads straight to Luxembourg City. This new section should be accessible to motorists from Monday, 29 May 2023.

It will initially only be open on one lane. The bypass between France and Luxembourg will be fully accessible to traffic by the end of July, just before the construction industry's collective holiday. Following that, the signalling and IT systems will be tested.

When completed, the Micheville link will be 2.5 kilometres long. The speed limit on the section will remain at 90 km/h.

Construction of the link between France and the Grand Duchy began in 2006. The bypass's construction should have been completed four years ago.
