Regular maintenance of motorway tunnels across the country has begun and will continue until the end of October. Motorists should expect partial closures over the coming months.

Twice a year, preventive and repair works on safety equipment (including fire or accident detection, lighting, video surveillance, and others) are carried out by the national road and bridges administration.

The second motorway tunnel maintenance and cleaning campaign for this year began this week and will last until the end of October. Most works are carried out at night to limit disruption. The planned dates of the works for the different tunnels can be consulted on the CITA .

Tunnels and game crossings that will be inspected include: Grouft, Rëngelbour, Stafelter, Gousselerbierg, Mersch, Roost, Colmar-Berg, Schieren, Howald, Cents, Richard Serra, Kirchberg, Saint-Esprit, Pénétrante Sud, Merl, Pétange-Eglise, Biff, Accès Secondaire, Micheville, Aessen, Ehlerange, Foetz, Frisange, Mondorf and Markusberg.
