The A1 motorway was backed up around the capital on Wednesday afternoon, with traffic building up in the direction of Trier.

The Roads and Bridges Administration reported a mobile construction site underway between the Howald tunnel and the Sandweiler/Hamm exit, blocking the right-hand lane of the motorway in order to carry out the works.

Traffic had therefore formed for several kilometres back to the Croix de Gasperich, while the speed limit has been reduced to 70km/h for this stretch of motorway.
