Much of the work at that stage was done by the Brenta guides of that era: Bruno Detassis and Enrico Giordano. The itinerary completed two years later enabled climbers to reach the apex of the Campanile Basso Via Normale. The works were interrupted by the Second World War but were resumed in 1948 mostly by effort of Celestino Donini, until reaching its completion point at the Bocca dei Armi. Later, in 1968-'69 the itinerary was extended towards the Bocca del Tuckett by a trajectory called Via delle Bocchette Alte, a challenging itinerary that reaches a quota of 3002 meters and traverses the Cima Brenta east face just under the summit. At a later stage the itinerary of vie ferrate was extended towards Passo del Grostè by means of the Sentiero Benini and still later on extended further over the Northern Chain towards Rifugio Peller: Sentiero Costanzi.
