The New Port of Buenos Aires was completed in 1926, making the existing Madero docks superfluous. Though these continued to serve in ancillary port functions, the zone gradually decayed, becoming one of the city's most degraded areas, a mixture of warehouses and large tracts of undeveloped land. In 1925, 1940, 1960, 1969, 1971, 1981 and 1985, successive proposals were put forth with the intent of urbanizing the old port, or to demolish it outright; none of these plans came to fruition, however.
