On Thursday 22 October 2026, Luxembourg's Ministry of Mobility and Public Works provided an update on the planned Alzingen bypass, a €390 million infrastructure project aimed at reducing traffic congestion in Hesperange and improving mobility in the south-east of the Luxembourg City metropolitan area.
The ministry reported that the parliamentary Committee on Mobility and Public Works had examined the project's financing bill. The government approved the project on 15 May 2026, followed by a favourable opinion from the Council of State on 30 June 2026. The bill is now progressing through the legislative process in the Chamber of Deputies.
"Preparing tomorrow's mobility means investing today in infrastructure that meets the needs of future generations. The Alzingen bypass is a major project for the entire south-eastern part of the Luxembourg City metropolitan area and Hesperange. It will help distribute traffic flows more effectively, improve the living environment for local residents and sustainably support the area's economic and demographic development. Construction is no longer simply about building infrastructure; it is about preparing the Luxembourg of tomorrow for the benefit of our citizens," said Yuriko Backes, Luxembourg’s Minister for Mobility and Public Works.
The bypass aims to redistribute traffic in an area used by more than 20,000 vehicles daily. It is intended to reduce through traffic in central Hesperange and surrounding residential neighbourhoods while supporting the development of Cloche d'Or, Ban de Gasperich and Midfield.
The planned 5.75-kilometre bypass will feature one lane in each direction and twelve engineering structures, which will account for nearly 40% of the route. The project also includes a cycle path parallel to the CR159 and traffic-calming measures intended to encourage cycling and walking.
Furthermore, the ministry said that environmental integration is a central element of the project. The plans include restoring the Alzette River and its tributaries to a more natural state, as well as modifying the nationally protected Réiserbann area, two measures considered essential for the project's implementation.
The project will also include numerous measures to support biodiversity, ecological corridors, species protection, water quality and the reduction of environmental disturbances, added the ministry.
The estimated €390 million investment will be financed through Luxembourg's Roads Fund. According to the ministry, the construction schedule reflects the project's technical, environmental and administrative requirements, with completion expected around 2037.
