The summer of 2026 is set to be a hectic one for the thousands of commuters who pass through Kirchberg every day. With the tram extension, the closure of the Schuman Tunnel and a number of traffic restrictions, one of the country’s main transport hubs will be operating at reduced capacity for several weeks.
From 22 July to 9 August, tram services will be suspended between the Rout Bréck – Pafendall and Philharmonie – Mudam stops. This disruption, which is geographically limited but strategic for the network, is essential to connect the first extension of the tram line to the existing line at the junction of Avenue John F. Kennedy and Boulevard Konrad Adenauer, explains the ministry of Mobility and Public Works.
In practical terms, the tram will continue to run on both sides of the construction site. Passengers will be able to travel from the stadium to Rout Bréck – Pafendall towards the city centre and, in the opposite direction, between Philharmonie – Mudam and Luxembourg Airport. Passengers will need to walk between the two temporary termini. A safe 450m route will be provided, but passengers are advised to allow up to 15 minutes extra for their journey.
Disruption on the roads too
However, the disruption will not be limited to the urban rail network. From the evening of 22 July until 15 August, part of Konrad Adenauer Boulevard will be closed to traffic, even though it has already been a one-way street since 3 May due to tram works. Several AVL bus routes, including routes 6, 16, 18, 21 and CN5, will be diverted. Stops serving the European Investment Bank (EIB) directly will be temporarily suspended, with alternative stops provided instead.
At the same time, another major construction project is set to reshape travel patterns in the capital. The Schuman Tunnel will be completely closed from 10 July to 14 August. The Public Works Department will use this window of opportunity to modernise the tunnel’s facilities, repair certain structural elements and prepare for future road resurfacing works scheduled for 2027.
Work will be carried out continuously, 24 hours a day, seven days a week, in order to minimise disruption over the shortest possible period. Motorists travelling from Belgium or France will be advised to use alternative routes to reach Kirchberg, whilst several regional bus services will be diverted. This is whilst train services between Luxembourg and Bettembourg will also be cut this summer.
