Rengelbur Ecoduct (wildlife crossing)
A wildlife crossing on the Route du Nord
Construction of the “Rengelbur” wildlife overpass as part of the construction of the Route du Nord on the W interchange section.
With a length of 150m, the overpass consists of a double open frame type structure in reinforced concrete and has three juxtaposed tunnels. The central tunnels carry the Route du Nord and Mersch bypass traffic, while the west tunnel takes over the two-way traffic from the diverted N7.
The wildlife crossing was built using the cut and cover method. In other words, the work involved conventional excavation for the tunnel frames, followed by backfilling around and on top of the slab in order to restore the local vegetation.
The rounded shape of the discharge outlets meets the crossing requirements for large animals.
