Alpiq and Kummler+Matter provide lighting for the A13 tunnel near Roveredo

A total of 700 lights were installed by the fitters from Alpiq InTec and Kummler+Matter in the new bypass tunnel near Roveredo in the canton of Graubünden. The tunnel and the demolition of the old road that cuts through the centre of the village will increase the quality of life for the local population: a first for Switzerland!
