Countdown at the Lötschberg

Four days before the official first blasting at the Lötschberg: the Ferden access tunnel near Goppenstein is driven further into the rock. (1999, AlpTransit Gotthard Ltd)

Construction of the NRLA is officially deemed to begin with the first blasting for the Lötschberg Base Tunnel on 5 July 1999. The first blasting at the Gotthard takes place on 4 November 1999. These dates are important for politicians and the general public, who follow construction of the new tunnel with great interest; but exploratory borings had already been carried out at both locations as far back as 1993. These in turn have their origins in the project planning from the mid-1980s.
