Luxembourg Parliament Reviews Major Infrastructure Projects as Public Works Surge

On 27 November 2025, deputies from the parliamentary committees responsible for budget execution and public works convened to assess the state’s largest ongoing and planned infrastructure undertakings. The meeting, bearing special oversight, focused on projects whose costs exceed €30 million and are managed by the public buildings administration or the national bridges & roads authority.

Among the public-building projects under review: a vast renovation and upgrading plan for the national military centre at Herrenberg (budgeted at €192.1 million), expansion of the penitentiary facility at Uerschterhaff (€173.9 million), and conversion of the old national library into a modern facility (€56.7 million). The list also includes several major educational investments — such as new or upgraded high-schools (including a large-scale “Neie Bouneweger Lycée” at €312.9 million), international schools, and technical-vocational institutions across the country — along with social infrastructure like youth hostels, care homes and community facilities.

On the transportation side, the meeting examined numerous road and mobility-infrastructure plans. These span from multimodal transit hubs and park-and-ride facilities, to large projects such as expanding highway A3 to three lanes (estimated cost: €501.5 million), building bypasses for towns like Hosingen, upgrading junctions on major highways, and roadworks on key national routes. Other plans include enhanced cycle-path links, renovation of the Adolphe bridge access, the establishment of a new traffic-control centre, and major hydropower and water-management works — reflecting a broad portfolio covering mobility, infrastructure modernisation, and environmental adaptation.

Deputies also raised issues beyond financing: during the exchange, questions emerged about traffic-management, real-time communication to road users regarding congestion, and the introduction of carpool lanes. Some opposition members expressed concern over privacy protections around proposed use of technology to monitor vehicle occupancy.

The session underscores Parliament’s tight oversight of public-works investment, as well as the scale and ambition of state-led infrastructure renewal across education, defense, transport and public services. As many of these projects run into hundreds of millions of euros in expenditure, their follow-up remains central to Luxembourg’s long-term mobility, urban planning and public-services strategy.
