On Tuesday 10 November 2026, Luxembourg's Roads and Bridges Administration announced that, as part of the next phase of the redevelopment of the Pontpierre interchange, it will close a section of the A4 motorway between the Cessange interchange and the Esch junction from Friday 13 November until Monday 16 November 2026.
According to the administration, the closure will be in place from approximately 20:00 on Friday until around 04:00 on Monday, with the works scheduled over the weekend to minimise traffic disruption during the working week.
The following access points will be closed:
- the slip roads from the A6 motorway at the Cessange interchange onto the A4 motorway towards Esch-sur-Alzette;
- the access road from the Leudelange-Nord interchange towards Esch-sur-Alzette;
- the access road from the Leudelange-Sud interchange towards Esch-sur-Alzette.
Road users wishing to access the A4 motorway from the Cessange interchange will be diverted via the A6, A3 and A13 motorways.
Road users wishing to access the A4 motorway from the Leudelange-Nord or Leudelange-Sud interchanges will be diverted via the N4, the A4 towards Luxembourg, the A6, A3 and A13 motorways.
The preparatory works required for the motorway closure will be carried out several hours before the start of the roadworks.
Traffic disruptions are therefore expected from late Friday afternoon.
Additional details of the closures can be found at: CITA – Roadworks.
