Luxembourg's tunnels are all set for their bi-annual maintenance works, beginning next week from Monday 9 March 2020.
These works include the preventive and curative maintenance of safety equipment, such as ventilation, fire detection and extinguishers, tunnel lighting and radio transmission, among others, as well as the operation and interaction of the various equipment and the upload of alarms to CITA, and the cleaning of the tunnel walls.
Depending on the size and complexity of the tunnels and taking into account the impact on traffic and coordination with other sites, maintenance will be carried out mainly overnight and spread over one or more days. The maintenance period will run until the beginning of June 2020.
The tunnels and passages concerned are as follows: 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.
