Luxembourg's Roads and Bridges Administration has announced overnight closures on the A13 motorway between the Differdange interchange and the Biff roundabout from 21:00 until approximately 05:00 on the nights of Tuesday 28 to Wednesday 29 July and Wednesday 29 to Thursday 30 July 2026.
According to the authorities, the closures will allow construction work on a wildlife crossing to continue. They will affect the section of the A13 between the Differdange interchange and the Biff roundabout (towards the Biff roundabout), as well as the section between the Biff roundabout and the Sanem interchange (towards Esch-sur-Alzette).
The closures will also affect access to the A13 from the Biff roundabout towards Esch-sur-Alzette, and from the Differdange and Sanem interchanges towards Pétange.
Traffic heading towards Esch-sur-Alzette will be diverted via the N31, CR175A, CR175 and the Sanem interchange.
Motorists travelling towards Pétange will be diverted from the Differdange interchange via the N32, CR174 and N31, while those joining from Sanem will be redirected via the CR175, CR175A and N31.
Further details of the closures are available on the CITA website.
