Why this spot

From 1978 to 1984 the city dumped demolition rubble from the motorway clearances into the river to build a never-finished civic centre; the Rio de la Plata now washes a shore of old house rubble.

Wikipedia and Canal 26 (2026) document the embankments built from demolition debris of houses razed for urban motorways, dumping to 1984 and the 1986 reserve ordinance; the rubble edge is visible from the river trailsView source →
