Redevelopment of the Dudelange-Burange interchange, located at the intersection of the A13 motorway and the N31 national road, is part of the development of the local road network relating to the extension of business parks and urbanization areas along the Collectrice du Sud. The construction of activity zones in the North (Eurohub + CFL Multimodal Platform) and in the South (National Health Laboratory) leads to an increase in traffic that no longer allows the interchange, due to its geometric configuration, to meet safety and capacity requirements. The redevelopment of the existing interchange has two main objectives. On the one hand, it is intended to provide easy and direct access to the motorway for the planned business and urban development zones in the vicinity. On the other hand, it aims to increase the capacity and safety of this heavily loaded road junction. The designers chose a solution with reinforced soil structure due to the environmental friendliness and due to the most cost-saving solution. The support provided by Maccaferri together with the partner Texion was very well appreciated by the designers and the construction company during the pre-design and construction phase.
