On March 10, 2011, work begins on the wild-animal corridor at Dosso di Taverne. The companies comprising the Lot 815 Consortium are Ennio Ferrari and Mancini&Marti SA. The contract value is approximately 6 million Swiss francs. The work is scheduled for completion in autumn 2012.
Construction of the Dosso di Taverne Corridor will restore the east-west wild-animal migration route. This is of super-regional importance and currently interrupted by the railway line, cantonal road and A2 motorway as well as the AlpTransit construction site at Sigirino.
The wild-animal corridor is one of many environmental protection measures that are being implemented along with construction of the NRLA.
