Luxembourg’s Roads and Bridges Administration announced on Wednesday 22 July 2026 that the section of the A13 between the Differdange interchange and the Biff roundabout will be closed from the evening of Friday 24 until the morning of Monday 27 July 2026.
The administration stated the closure is a result of the ongoing construction of a wildlife crossing on the A13.
Accordingly, the A13 between the Differdange interchange and the Biff roundabout (towards the Biff roundabout), as well as between the Biff roundabout and the Sanem interchange (towards Esch-sur-Alzette), will be closed from 21:00 on Friday 24 July until approximately 04:00 on Monday 27 July.
As a result of the works, the following access points will be closed:
• access from the Biff roundabout to the A13 towards Esch-sur-Alzette;
• access from the Differdange interchange to the A13 towards Pétange;
• access from the Sanem interchange to the A13 towards Pétange.
Users wishing to join the A13 towards Esch-sur-Alzette will be diverted via the N31, the CR175A, the CR175 and the Sanem interchange.
Users travelling towards Pétange will be diverted from the Differdange interchange via the N32, the CR174 and the N31, or from Sanem via the CR175, the CR175A and the N31.
