A major reconstruction project is transforming one of Dudelange's busiest roads, with the €6.5 million overhaul designed to slow traffic, improve safety, and make the area greener.
Work on Route de Boudersberg began in June 2025 and is expected to be completed by the end of 2027 or early 2028. The roughly one-kilometre stretch is an important traffic artery in southern Luxembourg, but years of heavy use have taken their toll, particularly on the road surface, which has repeatedly been given temporary repairs.
Much of the current work is taking place underground, with utility networks being completely renewed. Every individual home has to be reconnected, while new sewer pipes are also being installed.
Ralph Di Marco, spokesperson for the National Roads Administration, explained that the project involves coordinating work on wastewater, water, gas, telecommunications, and other utility networks at the same time.
"Part of a garage entrance sometimes has to be dug up to make the connection, and of course we then have to repair it again", he said. "It has to be done house by house, and that naturally takes time."
Once completed, the road will also be significantly calmer in terms of traffic, an important consideration given the presence of a primary school in the area. Speed limits of 20 and 30 km/h will be introduced along different sections of the route.
Claudia Dall'Agnol, Dudelange alderwoman responsible for mobility, said a 30 km/h zone would be introduced near the school to improve safety for both pupils and teaching staff.
The municipality also wants to add more greenery to the street, she explained, something she said had become increasingly important given the high temperatures experienced in recent weeks. Light-coloured asphalt will also be used to help reduce heat build-up.
"It doesn't just look good; it also helps prevent the area from becoming quite so hot", Dall'Agnol said.
Further up the road, near Mont Saint-Jean, a 20 km/h residential zone will be created, she added, with a shared path for cyclists and pedestrians also planned along the entire length of the project.
The reconstruction is being carried out in seven phases. Work is currently under way on two sections between Rue des Champs and Route de Kayl, with sewer construction taking place on one stretch and utility works on another.
Di Marco said part of the new pavement had already been completed on one side of the road, with further work on that section due to be finished before Luxembourg's annual construction holiday begins on 31 July.
Despite the scale of the works, the road is never completely closed to traffic. Public transport is also being maintained throughout the project, although buses are currently subject to diversions and cannot operate in both directions along the affected stretch, according to Dall'Agnol.
Dall'Agnol said further changes to routes may be necessary as construction progresses, but stressed that maintaining public transport connections remained a priority.
"We always try to make sure that everyone can still reach the centre of Dudelange and travel beyond it, including towards Schifflange and Esch-sur-Alzette", she said.
The total budget for the reconstruction amounts to €6.5 million. Two-thirds of the cost will be covered by the municipality of Dudelange, with the state funding the remaining third.
