Although work on the future wildlife crossing is seeing good progress, drivers must prepare for a much narrower road once construction enters the next phase.
French border crossers driving on the A31 and A3 every morning for the last weeks have surely seen the gradual growth of the "Neie Wal".
Slowly, the curve of the future wildlife bridge is taking shape on the edge of the A3 in the direction Luxembourg-France, right on the border.

On Saturday, construction workers began installing the second of five sections that will carry the weight of the 67-metre long and 40-metre wide vault over the motorway. In a few weeks, the operation will be repeated on the other side of the motorway towards Luxembourg.
"We are doing everything possible without penalising traffic," says Alain Guastalli, head of civil engineering.
However, the next step will inevitably lead to a further narrowing of the road on both sides. Behind the crash barrier, in the middle of the roadway, a 70-metre long concrete foundation is currently being installed.
Over the course of the coming months, workers will focus on the half shell that the future footbridge will form above the motorway. The motorway "will not be closed, except when concreting at night," explains Guastalli.
However, during the construction of the metal gantry, all the traffic will be "shifted once on one side and once on the other, each time for a weekend," warns the project manager.
