From Friday 13 November to Monday 16 November 2026, two sets of roadworks will affect travel in the south of the country and in Luxembourg City. On the A4, access roads towards Esch-sur-Alzette will be closed around Cessange and Leudelange. In Val de Hamm and on part of Boulevard Général George S. Patton, traffic will be interrupted and several bus routes diverted. Timings and routes differ by area: checking them before setting off will help avoid confusing the two arrangements.
A4: access roads towards Esch closed from Friday evening
The Administration des ponts et chaussées plans to close the section between the Cessange interchange and the Esch junction from around 20:00 on Friday 13 November until 04:00 on Monday 16 November. This phase is part of the redevelopment of the Pontpierre interchange. The timings are provisional.
The closure includes the A6 slip roads at the Cessange interchange that allow drivers to join the A4 towards Esch-sur-Alzette, as well as the Leudelange-Nord and Leudelange-Sud access roads in the same direction. The notice lists these access roads towards Esch: they are the reference points for the announced diversions.
From the Cessange interchange, the diversion route runs via the A6, A3 and then A13. From Leudelange-Nord or Leudelange-Sud, follow the N4, join the A4 towards Luxembourg, then take the A6, A3 and A13.
Preparations for the closure are due to begin a few hours before the roadworks. The Administration des ponts et chaussées warns that disruption is possible from late Friday afternoon, before the announced closure time.
Val de Hamm and Boulevard Patton: two sections closed
In Luxembourg City, the closure is scheduled from 20:00 on Friday 13 November until 05:00 on Monday 16 November, according to the City’s notice. Val de Hamm will be closed to all traffic between Rue des Peupliers and Rue de Pulvermühl. Boulevard Général George S. Patton will also be closed between Rue de Pulvermühl and Rue du Fort Dumoulin.
These restrictions apply to the specified sections, not the whole Hamm neighbourhood. The municipal notice says that signs will be put up on site.
Buses: changes vary by route
Route 7 will be diverted via Hamm. The Pulvermuhl-Hammer Dällchen and Général Patton stops will not be served during the roadworks.
Route 29 will also be diverted via Hamm. The Pulvermuhl-Hammer Dällchen, Général Patton and Al Molkerei stops will be replaced by the Huese Vic stop. In the direction of Senningerberg, there will be another change: Al Avenue Quai 1 will be replaced by Wallis Quai 2.
For route CN3, the diversion starts at the Englebert Neveu Quai 2 stop, then runs via Rue Englebert Neveu, Rue de Hamm and Bonnevoie. The Hamm-Colonie, Hamm-Schoul, Hamm-Kierch, Peupliers, Pulvermuhl-Hammer Dällchen, Général Patton and Al Molkerei stops will be replaced by Englebert Neveu Quai 1. The departure platform for the diversion and the one listed as its replacement are therefore different.
The changes do not apply in the same way to every route: a stop omitted on route 7 is not necessarily replaced in the same way as on route 29 or CN3. Passengers boarding in Hamm are advised to check the exact route and direction before heading to their usual stop.
Two timetables to bear in mind
The A4 road restrictions are due to end at around 04:00 on Monday, while those in Val de Hamm and on Boulevard Patton are scheduled to continue until 05:00. The reopening time for one area therefore cannot be applied to the other. The notices also concern separate projects: one involves the Pontpierre interchange, the other road resurfacing in Luxembourg City.
Before setting off, check the latest notices from the Administration des ponts et chaussées for the A4 and from the City of Luxembourg for the streets and buses.
