Buenos Aires Great Southern Railway
By 1899 the expansion of the Buenos Aires Great Southern Railway reached the station that later would become Cipolletti. To continue to the Neuquén Territory, a steel railway bridge was constructed in 1899–1902 to cross the Neuquén River. After the railroad connected Neuquén Station on the Confluencia settlement, the capital of the Territory was moved to the area, and the city of Neuquén founded in 1904.
