The interchange moves up a gear

The first phase, to be launched in July 2023, involves redeveloping the motorway exit from Esch, creating an access ramp towards Luxembourg, and widening the motorway to add a traffic lane and hard shoulder. Added to this is the creation of the future tramway line, the construction of a ‘turbo’ roundabout under the motorway bridge, the building of a hydraulic structure to allow the Mess to pass under the motorway and the refurbishment of a 5,000 m² retention basin.

The tram is coming! 

‘The earthworks have been completed and we have almost finished the retaining wall at the exit from Foetz. On route 39 (the entrance to Luxembourg), part of the wall is already in place and we will soon be incorporating the tram's dedicated facilities, such as its stop and access points,’ explains Yannick Dusanter, works manager. Good news for motorists: the Pontpierre exit will reopen before the summer holidays.

Other tasks were added to the works. ‘We were asked by the Ponts et Chaussées to install 470 metres of noise barriers between the new exit to Luxembourg and the service station. This involves earthworks and the creation of foundations. In addition, we are carrying out network development work for the municipality of Wickrange, particularly in the Grand Frais area.

Respecting the ecosystem

Our teams had to work quickly to complete the hydraulic structure designed to channel the Mess before spring, so as not to disturb the ecosystem. ‘We first erected the walls of the structure, then used a formwork cart to pour the slab, without ever touching the water to avoid any pollution. It was also crucial to avoid creating obstacles in the event of flooding, so as not to impact the upstream part of the stream. Objective achieved: the Mess has returned to its natural course!
