It was designed by the architect Ernesto Estrada in 1938 together with the Centro Civico, as part of the same urban remodeling project undertaken by National Parks in the period 1934-1944. This important avenue, with high landscape value in the tourist road to Llao Llao, connects with Bustillo Av and runs for about 2 km, from Plaza Perito Moreno up to the Monolith tribute to San Martín. The two streets are divided by a tree-lined pathway with a stone wall. It allows interesting panoramic views towards the lake and the mountains. Some emblematic buildings of the picturesque architecture were built in stone and wood on the south sidewalk: National Park Transportations, 266 School, Cathedral, Centro Civico.
